 A Ruby command-line program that will take coordinates and return either a unmasked gene sequence or a snp-masked sequence. The coordinates refer to the start and stop positions, and are "UCSC coordinates" i.e. 0 based and half open (see [UCSC_coordinate_transforms](http://genomewiki.ucsc.edu/index.php/Coordinate_Transforms))
