RGMergeBAM : Merge multiple BAM files appending ReadGroup IDs

rgMergeBam merges multiple sorted BAM files into one BAM file like 'samtools merge' command, but merges BAM headers.

• Checks that the HD and SQ tags are identical across the BAM files
• Adds @RG headers from a tabular input file containing the fields' info
• Adds RG:Z:[RGID] tag for each record based on the source BAM file
• Ensures that the headers are identical across the input files and that input/output BAM records are sorted
