WIP: testing sympy solver

looooo commented 6 years ago

some first tests with sympy (trying to constraint 2 simple boxes, point to point-constraint):

I guess the sympy solver is pretty broken now. I'll get it back online after the next release.

great looking forward to test it.

@realthunder this issue is being de-prioritized? (just asking)
