* a bit of header cleanup
* Fixes#1106
* First pass, basics.
Still need tests and handling of parameters.
* initial pass at including JSON parsing of options (not complete)
* handle errors while parsing json instead of just crashing the server
* updated (and working) JSON configuration
* first drawing tests
* document the new function
* it helps to save before committing
* Fixes#982
also changes bond-wedging algorithm to favor lighter non-ring bonds
* prefer wedging bonds to lower-degree atoms
* Fixes#983
* small fixes
- Fix a problem where a chiral atom is selected to draw a wedge to instead of a ring atom
- Fix a problem where two calls to PrepareMolForDrawing() led to two wedged bonds from an atom.
* Fixes#985
This isn't the most satisfying solution (the wedged bonds are sometimes a bit too large), but it gives reasonable results on the test cases I've tried.
