add test two test examples for asvd and adapt method that evaluates the rank
added qr_full to find orthogonal complement of the U and V factors of the SVD, when rank r < M
added M > N support to the SVD
add support for N < M to SVD
used 2to3 to make algopy Python 2 and Python 3 compatible
apply 2to3 to ./documentation and ./experimental
update setup.py classifiers and MANIFEST.in
remove builtins reference from setup.py (what was it used for?)
add .travis.yml file for testing on travis-ci.org
