BF: Small fix to make travis go.
RF: Remove dipy dependency by integrating the NIPY onetime module.
RF: get coverage.
BF: Two different things:

1. Seems that MakeFastPrediction was replaced with MakeFastGaussPrediction.
2. Reduce sensitivity of testing utils, for other platforms (Travis).
RF + TST : Add a coveragerc, so that only popeye is tested.

Reduce sensitivity even more.
TST : make sure that doctesting example works.
TST : experimenting with coveragerc
TST: experimenting with coveragerc some more.
TST: Maybe this will restrict test coverage for us?
Just kicking the golem into life.
