Adds geometric series with new solver.  Removes references to Pareto distribution; should use discrete Zipf distribution, probably interfaced with R.
Adds Xiao's zipf_functions to .gitignore file.
Merge remote-tracking branch 'upstream/master'
Sets upper bound for geometric series to be total community abundance.  Still getting an error for that, though.
Updates README to remove unused dependencies, additional information about models used.
Updates model documentation within package.
Add information about installing METE and macroecotools modules.
Removes extraneous variable from call for analysis module.
Removes problematic geometric series and references; also removes references to Zipf distribution.
Fixes output error.
Fixes output error.  Something is wrong with the analysis code and the CBC data, so this is BBS only."
Merge branch 'master' of https://github.com/embaldridge/sad-comparison
Removes results print statement.
Removes references to geometric and Zipf distribution.
Changes how results2 (dist_test.csv files) goes about formatting the data.  For some reason, the original method was working for BBS and NABA datasets, but was breaking for the Gentry data.  New method seems to work for all three of those datasets.
Adds geometric distribution back in, removes error chasing print statements. Generalized Yule sometimes returns none for a, b; need to determine how to handle this result.
Adds geometric series to documentation.
Adds geometric series to README.md.
Rearranges code so that all operations for each model occur in the same location (solve distribution, calculate likelihoood, calculate AICc).  Also raises an exception if generalized Yule does not converge, and skips site.
Moves the generalized Yule to the end of the distributions, modifies header to reflect this change, skips generalized Yule while still calculating AICc weights for the rest of the models.
