Made changes to the coauthor part of the code to compare both name and id, to solve a bug that was rendering user co author graph unusable for many users. Also making changes to the trust processor so that it is file dependant.
Wrote a function in dblptrustprocessor that takes an author name and a year and gives the author's trust value before that year.
Added field attribute parser and Jaccard algorithm
Finished the code to calculate the shortest path between authors, based on time. It is in the coauthorgraph file
