genome-bin-tools

Created new object classes gbt and gbtbin to replace genomestats, diffcovstats, genomestatsbin, and diffcovstatsbin classes. All coverage data from various samples for a single assembly are now stored together in the same object. This is more natural and easier for the user. Switching between plots of different sample coverages for the same assembly is much easier, and no fussing about with additional functions is necessary.
