Fixes for dataprojections
Distance vector sign was updated in previous commits by setting: 
distanceVector(1:numberOfCoordinates)=interpolatedPoint%values(:,NO_PART_DERIV)-dataPointLocation 
and by multiplying gradient and Hessian values by -1 compared with the
original implementation. 
However, with the updated code, the gradient values are the same as what
the old code produced, however the Hessian isn't. Fix was to revert to
the original implementation for the gradient and Hessian and setting the
distance vector as: 
distanceVector(1:numberOfCoordinates)=dataPointLocation-interpolatedPoint%values(:,NO_PART_DERIV)
 This has been done for all cases of the projection (line, face,
element).
