revert DecomposerBase such that its internal matrix methods are outside the class (fixes the performance issue); this addresses issue #15.
split example.py into example_fits.py and example_txt.py (before it only used a .txt example).
deleted the CUBISM-created .fits file, which was replaced with the correct .fits file (which had a _old.fits suffix). Also updated the accompanying README.md in the examples/ directory.
removed filename keyword from usage.rst and the example scripts.
corrected typo in academic reference.
updated usage.rst to use pkg_resources to match how pyPAHdb's code is used elsewhere.
I also think issue #10 can be closed, as the docstrings appear to be in order now (using the Google Docstring style).
