Changed switch statement to match actual agent variable
Edited the csv in a text editor to remove unnecessary commas
implemented categorical variables, working on interaction terms

check for interaction clause before doing the categorical variables
since "String agentVariable =
variableSynonym.get(statsVariable).toString().trim();" will throw an
error since the actual interaction term is not in the lookup table.  if
I encounter an interaction term, i split by the '*' and then look up
each term separately
