Description
Provide a top-level eval function, something like:
pd.eval(function_or_string,method=None, **kwargs)
to support things like:
-
out-of-core computation (locally) (see ENH: create out-of-core processing module #3202)
-
string evaluation which does not use python lazy evaluation
(so pandas can process effiiently)
pd.eval('df + df2',method='numexpr') (or maybe default to numexpr)
see also:

- possible out-of-pandas evaluation
pd.eval('df + df2',method='picloud')
http://www.picloud.com/ (though they seem to have really old versions of pandas),
but I think they handle it anyhow
