bracken

This module works with Bracken output files that resemble Kraken reports. They look like the following:

100.00	1188381	0	R	1	root
100.00	1188380	0	R1	131567	  cellular organisms
100.00	1188328	0	D	2	    Bacteria
99.99	1188317	0	P	1224	      Proteobacteria
99.99	1188308	0	C	1236	        Gammaproteobacteria
99.99	1188285	0	O	91347	          Enterobacterales
99.98	1188147	0	F	543	            Enterobacteriaceae

The main assumption to tell Bracken reports from Kraken is that the former don't have an "unassigned" category at the head of the file, and instead start with "root".

A bar graph is generated identical to that of Kraken.
