Bug fix

Identified a bug where pvalues were being artificially depressed in the function qiime.pycogent_backports.test.correlation_row_generator when Spearman was passed for otu_gradient_correlation.py. Specifically, it was counting the length of the data vector of interest as the same length even if there were exclusion criteria in place (i.e. that data vector had nans or empty sequences). The function as well as get_sample_cats has been updated to allow explicit exclusion criteria.
