Updated docs and round_case is now default

Round_case is default. Original box case is likely broken and should be removed.

 GearHinge is an openscad model of a geared hinge. This was developed as part 
 of another project, but stands on its own as a part that could be re-used.

 ## Status/Known Issues

+Under development, should be vaguely usable.
 
 1. Arms have no mounting holes for general use.
 2. No functions/workflow exists for attaching arms to anything else.
-3. Module is 1.45; it should be parametric. Hard coded values must go.
 4. Cannot be assembled or disassembled; must be printed in place.
 5. Helix angle can only do a single "turn". Should be re-written to use sin.
