#I should make an SOP for this.  Problems we encountered: no x in the xY motif, and the kilodemon
#the output files have both Y and xY, they shouldn't why is that happening?  make it not happen

#output should look just like the KALIP input

# better version of this code written in C: what happens when two kinases share a motif, but they found that motif in two 
# separate proteins thus two separate accession numbers?
# It should actually output the shared motif and BOTH accession numbers.  Right now it does not, it only maps out the second
# accession number.  So that needs to be fixed BUT you need to keep the commonality between a motif and its accession number
