Miter template enhancements

BikeCAD has always been capable of generating miter templates for a range of complex geometry from seat stays that attach at points offset from the center of the seat tube and at angles in multiple planes to elliptical top tubes and down tubes attaching to tapered head tubes to down tubes that are mitered to both the bottom bracket shell and the seat tube. Now, in version 20.0, BikeCAD will account for miters at eBike motor mounts or Pinion Gearboxes as well as seat stays and chain stays attaching to hooded dropouts.
