Normalize reads reported in counts.txt files to reads per 10mm

[cadley-nyulangone]

new reads reported = int(10,000,000 * (number of reads in the range) / (total reads from the sample) + 0.5)
                                       ============================
                                      This is what we currently report

total reads is computed this way:

    num_bam1_reads=$(samtools view -c -F 512 ${bam1})

It's set in line 65 of merge_bamintersect.sh

It's passed into counts_table.sh in line 33 there.
