Initial release of GearGen.XYZ

Initial release of GearGen.XYZ. This is a web application for creating gears, gearsets, and geartrains. It is a work in progress and will be updated regularly. Starting capacilities are external spur gears, and positioning the gears in a geartrain in a custom x,y grid system.
