implement spectral biclustering and spectral co-clustering
wrote tests
wrote methods for generating bicluster data
added option to return piecewise vectors
cast data in fit()
made internal functions private
use random state in test
removed pickle test
shorten first lines of test docstrings
use random state in preprocess tests
duck typing, minor corrections: spacing and typos
fixed exceptions and their messages
updated svd()
better array validation
use random state in data generator
tests reuse data generators
user may select svd method
Added to docstring
split spectral biclustering into two classes
removed unused code
