make sure that the path generators never get stuck in in infinite loop caused by floating point inaccuracies
 define a maximum recursion depth (20) for the PushCutter algorithm (i.e. maximum precision = 1/(1^20) of bounding box width)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@156 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 fixed a small nasty bug, that occours in the DropCutter for small values of "material allowance"
 
 Description: ODE did not take the "extended" drill shapes into account, when deciding, if
 collisions are possible. Thus the collide callback was never called.


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@155 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 use a calculated "safe height" instead of "utils.INIFINITE" for a boundary limit failure in DropCutter (otherwise it looks like a bug)
  - issue a warning once
