Outlier classes and Tests made for XYGraph outlier scanning.
Outlier classes and tests for BarChart outlier scanning is still incomplete. (Modified Thompson Tau's critical t values are being kind of hard to get exactly.)
Made changes to how DataSet works; split it up into two different classes. DataSet now manages the data, and is an intermediate container of X/Y/Z/whatever set of columned data the user wants to use. HeaderData is a container of the column names and types before they're actually populated with data. HeaderData, along with a Pair (now known as GraphPair), creates a DataSet via the "populateData (GraphPair p)" function in HeaderData. Most of the changes to the main code are done, save for GUI tests.
