Fixes Issue #26: Updated labs involved to include the Vega Thurber lab
Partial Fix for Issue #29.   Biologically & formally equivalent tree representations were being rejected by the test code.  After the fix trees with swapped sister nodes are treated as OK, since the choice is arbitrary anyway.
Fixes Issue #29:  tip is replaced with tip.Name in a list comprehension prior to passing to getSubTree, which resolves test failures
Removes print statements from test_make_test_datasets.  Note that an assertion is still needed for test_make_distance_based_tree_randomizer, but this will be resolved as a seperate issue
Removing unneeded stdout, and switching the verbose default for minor functions (where output is usually only useful in debugging) to False.
fix for issue #37

this addresses issue #37, but required that we move the data directory under the picrust library directory and reference it as package data in setup.py. this allows references to those files (e.g., in normalize_by_copy_number.py) to work when the user has installed PICRUSt with setup.py or by just adding the library code directory to their $PYTHONPATH.
added support_files to package_data

this will allow these files to be accessible even if PICRUSt is installed with setup.py.
updated default path to adhere to new location of data files
updated default path to input_count_table to reflect new location of this file
