Matt Williams bb87e9e628 Fix Ambient Occlusion Calculator to accept functors, functions and lambdas ...

By changing the 'pass by value' to be a 'pass by const reference' (and
adding some const qualifiers) the calculator can take any of the three
types.

Performance could be improved further using C++11 perfect forwarding to
pass the function on without changing a thing. I added a comment to remind
us of this.

Also added a test for passing a function and a (commented out) test for
passing a lambda.
