allowing any lists as inputs

[ctw]

Currently in some cases passing a list of alphas (rather than an array) raises an exception. This can be easily fixed and I'm happy to do it and submit a pull request, but wanted to check here first that a more flexible behavior is desired. Please let me know either way.

great - please test whether this works with the bootstrapping decorator

Sure -- can you merge my pull request (#70 ) that allows the unittests to run without errors? There's also another outstanding pull request (#66 ) that should probably be merged.
