update cmake for windows build
Adds raycasting ability using bullet for RigidBodyManipulator.
Merge branch 'collision-dynamics-integration' of github.com:avalenzu/drake into collision-dynamics-integration
Adds a test for raycasting.
Merge branch 'master' of https://github.com/RobotLocomotion/drake
Load meshes in `URDFRigidBodyManipulator`

Also fixes handling of collision elements so that the collision elements of
links with no "default" collision group are still parsed. Adds
`testURDFcollision` to check that `collisionDetect` returns the same
information for `RigidBodyManipulator` and `URDFRigidBodyManipulator`. Note,
the order of points returned, as well as the body indices are *not* the same
between these two classes. However, all the same collision pairs are checked.
Remove commented-out warnings

Load meshes in `URDFRigidBodyManipulator`
setup cygwin mex environment in bashrc (so it works through ssh as well)
more complex invocation of mex.  didn't actually resolve the problem, but I want it in the commit in case i ever need to go back to it
back to simpler mex invocation
Merge branch 'master' of https://github.com/RobotLocomotion/drake
cygwin env works for 2014a now
more robust path handling
Add `allCollisions` method - fast collision checks
Re-ignore upper-leg collisions in atlas_chull.urdf
