GO lens library for common operations

[kltm]

We discussed the probability of deprecating Gannet in favor of a simplified JS environment for GO use (think another pass at the GO contrib library in BBOP JS). The rational is something like:

GOOSE worked because SQL was a general language (skill transfer) for a model that fairly closely mapped to how one might model the problem. Solr (Gannet) is essentially URL manipulation for a highly idiosyncratic schema, which isn't particularly transferable or intuitive (at the level of somebody trying to query it).

This could be simply deployed in either AmiGO 2's REPL or node (if we put the packages in npmjs.org).
