Added minor functions

Added minor functions that help make verifying certain mathematical properties of the data easier.
Added final tables
Added naive co-occurrence testing

Added functions to facilitate testing the the tables with a naive co-occurrence approach.
Added tests for NaiveParser

Also modified the naive co-occurrence tool.
Minor change to solve error in naive_cooccur_tool.py
Major additions, minor modifications

Added ROC curve function as well as tests for it.
Modified the naive_cooccur_tool.py.
Modified the LSAResults parser to accomodate for the apparently new results formatting.
Updated tests
Modified roc_edge_count.py and tests

Modifications necessary to make sure that the ROC code would count edges properly in multiple events. Likely this code should replace the eco edge counter.
