Subject: [PATCH 03/45] Ensure that passing `settings=...` does not clobber the
 default `moduleId`.

Precompiling a template with `settings` previously generated a snippet
resembling `define(["undefined"], function(lodash) { ... })` if the `settings`
object did not contain a `moduleId` property. You can now pass `settings` and
`moduleId` options simultaneously; the builder will always use the `moduleId`
property in `settings` if it is provided, and default to `moduleId` otherwise.

 Creates a clone of `value`. If `deep` is `true`, all nested objects will also be cloned, otherwise they will be assigned by reference. Functions and DOM nodes are **not** cloned. The enumerable properties of `arguments` objects and objects created by constructors other than `Object` are cloned to plain `Object` objects.  Note: Lo-Dash's deep clone functionality is loosely based on the structured clone algorithm. See http://www.w3.org/TR/html5/common-dom-interfaces.html#internal-structured-cloning-algorithm.

+# Contributing to Lo-Dash
+
+If you'd like to contribute a feature or bug fix, you can [fork](https://help.github.com/articles/fork-a-repo) Lo-Dash, commit your changes, and [send a pull request](https://help.github.com/articles/using-pull-requests). Please make sure to [search the issue tracker](https://github.com/bestiejs/lodash/issues) first; your issue may have already been discussed or fixed in `master`.
+
+## Tests
+
+Please make sure to update the unit tests in the `test` directory as part of your pull request. You can run the tests from the command line via `npm test`, or open `test/index.html` in a web browser. The `test/run-test.sh` script attempts to run the tests in [Rhino](http://www.mozilla.org/rhino/), [RingoJS](http://ringojs.org/), [Narwhal](https://github.com/280north/narwhal), and Node, before starting your default browser. The [Backbone](http://backbonejs.org/) and Underscore test suites are included as well.
+
+We also use [Travis](https://travis-ci.org/bestiejs/lodash) for continuous integration.
+
+## Contributor License Agreement
+
+Lo-Dash is a [Dojo Foundation](http://dojofoundation.org/) project. **As such, we request that all contributors sign the Dojo Foundation [contributor license agreement](http://dojofoundation.org/about/claForm)**. You can [check](http://dojofoundation.org/about/claCheck) if you've already signed a CLA.
+
+For more information about CLAs, please check out Alex Russell's excellent post, ["Why Do I Need to Sign This?"](http://infrequently.org/2008/06/why-do-i-need-to-sign-this/).
+
+## Coding Guidelines
+
+In addition to the following guidelines, please follow the conventions already established in the code.
+
+- **Spacing**: Use two spaces for indentation. No tabs.
+- **Naming**: Keep variable and method names concise and descriptive. `index`, `collection`, and `callback` are preferable to `i`, `arr`, and `fn`.
+- **Quotes**: Single-quoted strings are preferred to double-quoted strings; however, please use a double-quoted string if the value contains a single-quote character to avoid unnecessary escaping.
+- **Comments**: Please use single-line comments to annotate significant additions, and [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for new methods. We use [Docdown](https://github.com/jdalton/docdown) to generate our documentation.

-If you'd like to contribute a feature or bug fix, you can [fork](https://help.github.com/articles/fork-a-repo) Lo-Dash, commit your changes, and [send a pull request](https://help.github.com/articles/using-pull-requests).

 ## Tests
 
-Please make sure to update the unit tests in the `test` directory as part of your pull request. You can run the tests from the command line via `npm test`, or open `test/index.html` in a web browser. The `test/run-test.sh` script attempts to run the tests in [Rhino](http://www.mozilla.org/rhino/), [RingoJS](http://ringojs.org/), [Narwhal](https://github.com/280north/narwhal), and Node, before starting your default browser. The [Backbone](http://backbonejs.org/) and Underscore test suites are included as well.

 ## Coding Guidelines
 
 In addition to the following guidelines, please follow the conventions already established in the code.
 
 - **Spacing**: Use two spaces for indentation. No tabs.
-- **Naming**: Keep variable and method names concise and descriptive. `index`, `collection`, and `callback` are preferable to `i`, `arr`, and `fn`.
+- **Naming**: Keep variable and method names concise and descriptive. Variable names `index`, `collection`, and `callback` are preferable to `i`, `arr`, and `fn`.
 - **Quotes**: Single-quoted strings are preferred to double-quoted strings; however, please use a double-quoted string if the value contains a single-quote character to avoid unnecessary escaping.
-- **Comments**: Please use single-line comments to annotate significant additions, and [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for new methods. We use [Docdown](https://github.com/jdalton/docdown) to generate our documentation.

 ## Tests
 
-Please make sure to update the unit tests in the `test` directory as part of your pull request.
+Include updated unit tests in the `test` directory as part of your pull request.
 You can run the tests from the command line via `npm test`, or open `test/index.html` in a web browser.
-The `test/run-test.sh` script attempts to run the tests in [Rhino](http://www.mozilla.org/rhino/), [RingoJS](http://ringojs.org/), [Narwhal](https://github.com/280north/narwhal), and [Node](http://nodejs.org/), before starting your default browser.

 ## Coding Guidelines
 
 In addition to the following guidelines, please follow the conventions already established in the code.
 
-- **Spacing**: Use two spaces for indentation. No tabs.
-- **Naming**: Keep variable and method names concise and descriptive. Variable names `index`, `collection`, and `callback` are preferable to `i`, `arr`, and `fn`.
-- **Quotes**: Single-quoted strings are preferred to double-quoted strings; however, please use a double-quoted string if the value contains a single-quote character to avoid unnecessary escaping.
-- **Comments**: Please use single-line comments to annotate significant additions, and [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for new methods. We use [Docdown](https://github.com/jdalton/docdown) to generate our documentation.

 Creates a function that, when executed, will only call the `func` function at most once per every `wait` milliseconds. If the throttled function is invoked more than once during the `wait` timeout, `func` will also be called on the trailing edge of the timeout. Subsequent calls to the throttled function will return the result of the last `func` call.

 A micro-templating method that handles arbitrary delimiters, preserves whitespace, and correctly escapes quotes within interpolated code.  Note: In the development build `_.template` utilizes sourceURLs for easier debugging. See http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/#toc-sourceurl  Note: Lo-Dash may be used in Chrome extensions by either creating a `lodash csp` build and avoiding `_.template` use, or loading Lo-Dash in a sandboxed page. See http://developer.chrome.com/trunk/extensions/sandboxingEval.html
