Tile is now a standard covariate. By default the TileCovariate returns -1 if tile can't be derived from the read's name. Added a new command line option -throwTileException which will force TileCovariate to throw an exception if tile can't be derived for a read. Singleton covariates, such as any read group without tile info, must be skipped over in TableRecalibration so that the sequential formulation doesn't apply the same correction more than once. TileCovariate class has been added to the Early Access package.
