Created 2nd random graphs did comparisons

11/18/14
Created a second random recommendation graph named recom-rand2.txt

Edited main function code to put recom-rand2.txt into a dictionary
called ids_with_recom_rand2

Edited the jaccardcompare and do_jaccardcompare to run jaccard compare
on new random graph
Added Cosine Sim function

Not sure how accurate it is.. only returning the vectors that have the
same number of elements between the arrays compared.
