adding new test to check integration of energy error/Riesz reps with computation of energy error thru the usual way
adding simpletest - currently set up to try anisotropic refinements
invisicid burgers test to check hessian with rhs
cleaning up rieszRep by using new functionality in basisCache
committing function changes - allows for specifying testVsTest for integration over teh whole mesh
added some code to try to take care of unrefinements in mesh. tested, not working
