Added functionality to write octree nodal position data to file.  Required added method in octree and node classes to recursively retrieve pointers to all child nodes
Linking and settings changes made by Xcode
Began constructing Constrained Hermite Taylor Series Least Squares class to be used in calculating the derivative of the potential.
Changes made to how neighbor search algorithm works.  Constrained Hermite Taylor Series Least Squares method written.  Still needs to be tested and verified.
Added VTUfile class for writing output files and removed temporary write functionality from runCase class
