Make documentation linkage between api names easier to find/see

First off, really effective wrapper and complete on all the Google APIs. No complaints from my usage so far.

This is very trivial, but for complete newbies like me, might be helpful. Remembering that Google has a lot to say about it's APIs that might not be captured in this documentation (and shouldn't be), e.g. if you include a region code in a Places request, the country name is excluded from formatted address. So . . .

Perhaps in documentation and/or code base doc strings, add reference to Google names for API? For instance, took me a long time to work through that "places" is the same as "textsearch" because "textsearch" doesn't appear in the code. A formatted print string separates "text" and "search", so references on repo pretty sparse.

Small idea. No big deal of course, but thought I'd try to contribute something back.
