Very minor: Snapshots -> Releases in SBT example.
state iterator and logging for ConjugateGradient. Fixes #83.
Merge remote-tracking branch 'scalanlp/master'
.gitignore from other machine... we'll merge.

let's do a weighted average of Adagrad's hessian.
STochasticAveragedGradient... we'll see how it does.
Ok, moved to the new netlib-java.

By default, we use pure-java implementations, though calling

if possible.

That was surprisingly easy.
sigh, that was a failed experiment
need to depend on arpack_combined_all to make things work.
cleanup based on suggestions by @fommil.
