Updated the file format to feed into Comet. Added a matrix to display the affinity stuff.

1) added total memory available per site and total sites per host to the first line \n 2) chnaged the heat computation to divide by the number of transactions as oppose to the number of batches \n 3) Added a second line after the first line for communication costs (need to fill them in later)

implemented the algorithm to give us the affinity (not percentage) between partitions. Partitions going to themselves still do *not* have an affinity 1 yet. Will double check on this

1) Hardcoded partition affinities to go to themselves as 1 2) excised printing the memory at each partition in the output file
