Should language document_from_text() etc. be a reference to the Document class

[dhermes]

See https://github.com/GoogleCloudPlatform/gcloud-python/pull/2062/files/d36ad4db94666450786d4f667aea0607ff2113cb#r76032786

The question is whether we should have Client.document_from_foo methods or just have Client.document be a reference to the class Document and then use Client.document.from_foo.

This amounts to swapping _ for . (i.e. no less typing) and makes a "proper noun" like Document be referenced as an "improper noun" as a property, which is not a win IMO

Hello!
We have done a less-than-great job of dealing with issues in this repository. Sorry about that. :-(

In this case, we have released an entirely different version of google-cloud-language, which is very likely to have solved this issue, so I am going and closing language-related issues en masse to try and regain sanity and ability to tackle things.

Please upgrade to the newest version of google-cloud-language and use LanguageServiceClient. Note that this will require a code change. If your issue persists, feel free to reopen. :-)
