Gateway API - Field Caching

[coreyo]

Implement local caching of field data so that it does not need to be re-requested from the SOLR database with every DwC Views request. Fields cache expiration time should be a dynamic, configurable option.

Yep. Django has fairly decent caching functionality - take a look and evaluate if that might provide a viable alternative to memcache. https://docs.djangoproject.com/en/dev/topics/cache/

This one is a can of pain. It would appear that most of the (useful) native django caching is broken with the google appengine. A solution that will work in both environments will require a coded hack in every place that calls the caching function.
