**What it does**

Takes one or more alignment files (BAM, SAM or tabular bowtie output) as input and produces a histogram of read sizes, 
where by default for each "chromosome" a histogram of read sizes is drawn. 
Reads that map in sense are on the top (red), reads that map antisense are on the bottom (blue).

'''TIP''' The input data can be produced using the sRbowtie tool.

'''Example'''

Query sequence::
For a SAM file as the following:

  5	16	2L_79	24393	255	17M	*	0	0	CCTTCATCTTTTTTTTT	IIIIIIIIIIIIIIIII	XA:i:0	MD:Z:17	NM:i:0

  2	16	2L_5	669	255	23M	*	0	0	TGTTGCTGCATTTCTTTTTTTTT	IIIIIIIIIIIIIIIIIIIIIII	XA:i:0	MD:Z:23	NM:i:0

produce a plot like this:
