Title: Bug solved in ankus-core when the input is not in tabular format

Hello, I am Jesús Morán

The progam has a bug when delimiter is not tab

For example, if the input dataset is formed by:
Richard,Spiderman,5
Richard,Batman,1
Richard,IronMan,4
Mary,Batman,2
Mary,IronMan,5
Steve,Spiderman,4
Steve,Batman,3
Steve,IronMan,2

And the similarity is formed by:
Mary,Richard
Mary,Steve

The program crash:

Mary Spiderman 4.5
