Integrate the best performing model and roleBasedEval into the same project

[ab-10]

The best performing model (F1 wise), is the one on commit 8533aa6, but the model on roleBasedEval branch offers comparison methods, that have future potential.

I would like to combine the analysis and indexation functionality of both of these models, so that the user can specify what type of analysis they want to do (the methods between the two should be in the same project, but separate methods).
