Several fixes for DMMoabCreateBoxMesh. Adding a fresh implementation of DMMoabLoadFromFile which works well. Both methods need testing in parallel but verified in serial.

Adding a first draft of utility functions for creating a structured mesh in memory using MOAB that can be used in applications directly in a dimension-independent fashion.

Adding DMSetFromOptions_Moab to unify all options database retrieval from command line. Added appropriate storage fields in data-structures and made sure that they are universally used, consistently.

Adding more documentation to all main source files and making sure the documentation is generated according to PETSc standards.

Rename some private function and add documentation to public API functions.

Fixing errors due to bad merge after cherry-picking earlier in the branch.

Adding an extra argument to box mesh creation in order to specify the domain bounds. Modifying examples accordingly.

Updating mbutil to the new moab interface change.

Feature additions and fixes. 1) Making the fileset by default represent root set. Useful when user handles the creation of mesh etc. 2) Renumber all entities after resolving shared nodes.

Getting the parallel mesh generation to work correctly. Generate extra sets to categories different dimensional entities so that we can apply some useful tags onto them in future.

Fix the NNZ computation by removing the old methods and implemented a more rigorous traversal to find nnz and onz. Other minor cleanups in DMMoab - remove prints, debug statements etc.

Fixing the parallel mesh generation using slices. The in-memory mesh has contiguous local and then ghosted entities. Tests successful.

Parallel mesh generation.

2b2088d: Ghost layer creation needs to be addressed for in-memory structured meshgen.
c5fa303: Owned vertex ranges might not always be contiguous when reading from files. N

51ee65e: Adding new public interface functions to simplify user assembly code. Added methods to get connectivity of an element, coordinates of vertices, and to check if given vertices lie on the boundary.
866cea9: Updating some RW options for MOAB and enabling command-line control.
fd2859a: Remove the DA related routines and references in 2-D example.

Make sure that all Global ids are 1-based. There is an internal call in DMMoab_SetUp to correct this to zero-based indices for suitable use in PETSc and other array related usage.
