# Comment: Program to plot gene structure
# Input: 1. input file of Gene region annotation which format like GenePred
#        2. input file of Transcripts region annotation which format like GenePred
#        3. input file of gene snp detail info
# Output: output file of gene structure graph by html or svg formt
