Escapement OpenSCAD Library w/ Test Jig Script

I cleaned up the code for my graham escapement script and broke it into two parts:
1. a library with the core modules (the wheel, the escapement), and
2. a little test script with the parameter values and some rough code throwing it all together into a little test jig

The library has all the modules needed to create a graham escapement that meshes properly with its escapement wheel. See instructions for a complete list, and see the library itself for a full list of parameters for each module.

The test script has the current candidate parameter values and provides two top-level modules:
1. an assembled() module that positions the parts in the fully assembled configuration, I hope to animate it in a future version.
2. a laidOutToPrint() module that positions the parts laid out flat, ready to print (assuming your printing platform is large enough, of course)
