RFC: Support non-Java language packages in BEF

[plaird]

As a Bazel Eclipse Feature user
I would like to use the BEF to develop my XYZ code (non-Java) in my Bazel workspace
Such that import of my Bazel workspace creates Eclipse projects for my BUILD file(s) with XYZ targets
Such that I can launch XYZ applications
Such that I can launch XYZ tests

Background:
The primary motivation for implementation of the BEF by the project authors (Salesforce) has been supporting Java teams. Currently this ticket is a request for comments for teams that would like to use BEF but use some language other than Java.

Please comment on this issue if you have non-Java projects that you would like to use with BEF. This issue is just a gathering point for discussion. Additional issues will be filed if/when any works begins on investigation/implementation of support for other languages begins.
