CNV map instructions in config file

[jdselwyn]

Need to update instructions because first column of pop.map file returns entire column name and the cnv file doesn't need the cutoffs.

popmap file:
FCOP-1_GAGTGG_L004.1.1-RG.bam FCOP-1
FCOP-2_GATCAG_L004.1.1-RG.bam FCOP-2
FMAT-1_GTTTCG_L004.1.1-RG.bam FMAT-1
FMAT-2_GTGGCC_L004.1.1-RG.bam FMAT-2
FSAN-1_TAGCTT_L004.1.1-RG.bam FSAN-1
FSAN-2_GGCTAC_L004.1.1-RG.bam FSAN-2

CNV file:
FCOP-1_GAGTGG_L004 10
FCOP-2_GATCAG_L004 10
FMAT-1_GTTTCG_L004 10
FMAT-2_GTGGCC_L004 9
FSAN-1_TAGCTT_L004 10
FSAN-2_GGCTAC_L004 9

I updated the config.4.all, leaving this open for now until I figure out exactly why this difference is necessary.
