2012-05-17: import and UCSC GENCODE group process of GENCODE V12 (markd)
    # Due to UCSC Genome Browser using the NC_001807 mitochondrial genome sequence
    # (chrM) and GENCODE annotating the NC_012920 mitochondrial sequence, the
    # GENCODE mitochondrial sequences are lifted to UCSC chrM.

    ## copy and update trackDb files from previous release

    ### IMPORTANT: make sure that hgTracks/simpleTracks.c registers
    ### track handler for this version of gencode:
    registerTrackHandlerOnFamily("wgEncodeGencodeV12", gencodeGeneMethods);
