Fixes https://sourceforge.net/p/pyparsing/bugs/106/.

With Python 3.7, I'm getting:

/usr/local/lib/python3.7/site-packages/pkg_resources/_vendor/pyparsing.py:943: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
  collections.MutableMapping.register(ParseResults)
/usr/local/lib/python3.7/site-packages/pkg_resources/_vendor/pyparsing.py:3245: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
  elif isinstance( exprs, collections.Iterable ):

This PR fixes it.

The tests pass for me on macOS High Sierra with Python 2.7 and 3.7:

Can this be submitted to TravisCI for verification? Looks like the PR predates my TravisCI integration.

Any chance for a release with this commit soon? The deprecation warning is very noisy in 3.7, and it doesn't sound like there's anything big blocking a release right now.

It looks like this is coming from the vendored copy of pyparsing in pkg-resources, which gets loaded with setuptools. I just looked at my environment, and I had the old pkg-resources until I pip updated setuptools, and now I have the necessary vendored version (pyparsing 2.2.1). Try reinstalling setuptools, and then check the vendored version of pyparsing in pkg-resources.
