Changed a couple of Activity calls to create_or_update to support newer, more granular Activities in GCIS. Added a method to list all known Activities

Removed hardcoded auth tokens and api keys from everything. Added support for env variables and config files for persisting credentials

Refactored HTTP requests to properly use Sessions to hold authenticate data.  Added support for associating contributors with figures and images

Added create_or_update methods to client. Disabled SSL verification on all webservice calls due to possible python SSL library limitation

Attempting to apply packaging best practices for *several* definitions of best practices. Sometimes I miss Java.  Sometimes.

Explicitly setting chapter_identifier field on Figure object during update. has_all_assoc_imgs now also returns the subset of images that are missing

create_figure() now explicitly sets the chapter_identifier on the outgoing Figure object since the API is apparently not inferring it from the url. Added function to check for presence of associated images in a figure to support problem-solving. Disabling SSL verification to work around a python bug

Added methods to test for the existence of certain entities without retrieving them. Now swallowing error code associating datasets with images when association already exists

Added better exception handling and more useful error messages (work in progress). Added ability to associate a dataset with a figure
