initial commit to Alex branch

added one comment so i could commit
improved camera broke ant movement

camera now will only move a certain distance from the ant
camera can has a maximum height
camera has a new collision detections so the ant can always be seen
working on improving the ant movement system so the ant is broken at the
moment
ant contour tracking

added "ant play ground" for testing out the movement algorithm
ant now tracks the surface bellow it and follows smooth transitions well
issues with angles around and over 90 degrees where the ant snaps to the
piece of ground bellow it
camera controller has a few bugs in it where it get stuck with a close
distance and close height
extra playground

added detailed mesh to the playground
fucked up the ant prefab and had to make it again
