#162 TASSEL discards hapmap file metadata

[jgwallace]

TASSEL does not retain the Hapmap-format metadata (columns 5-11). Though not used in genetic analyses, the metadata has important information on the SNP sources and should be maintained (at least by default). Included is a sample of the results, run with command:

run_pipeline.pl -fork1 -h input.hmp.txt -export output.hmp.txt -runfork1

Thanks.
