Merge branch '24-bug-in-roc-curves' into 'master'

Changed the ROC curve to implement what is required by 'The Handbook of Face Recognition'

Closes #24 

I have implemented the correct way to compute FRR values based on The Handbook of Face Recognition, i.e., counting positive scores that are exactly at the threshold to be correctly classified.
