[BioRuby] Developing a VISION

[Pjotr Prins]

## Vision statement: BioRuby is agile

The Ruby community is always working on agile processes. BioRuby can
benefit from behaviour driven development (BDD), specifications,
doctests and integration and unit testing.

Realisation: 

In addition to unit testing we should concentrate on introducing
Rspec, Cucumber, rubydoctests across the board. Also we should use the
continuous integration testing by services such as travis-ci (I have a
writeup on the latter soon) and perhaps use the OBF test services for
stable plugins.
