Starting by updating docstrins
validator renamed. A bit more docstrings updated
implemented and tested BagValidator
using forked version of schema since the original one does not interface well with future.builtins
testing that bags can also be tuples
transform and fit transform now are aware of bag-of-words, computing them as expected
BagValidator implements fitting as something separated from validation, so transforms does not modify it
small pep8 fix
fixed way of raising error
changed version to 0.1.1 and added notes to changelog
added test showing that transforming with unknown/unfitted word works ignoring such word
docstring update
test names updated for better understanding
documentation update
fixing typo
adding keywords and classifiers to setup.py
Merge branch 'bag-of-words-features' into develop
