Added 2-clause bsd license for cmake files requested in cmake script for
petsc.
Introduced cmake option for Mondriaan matrix partitioning package for
solvers.
Changed reading of solver's parameters database to fix uninitialized
access reported by dr.memory.
Fixed bug in svdnxn with static std::vector allocation.
Added features to OldDrawGrid example.
Added solutions to problems described in issue #13.

Fixed bug in auto-differentiation that would calculate incorrect weights
for derivatives in ad_val().
Adapted several geometrical and adjacency retrieval algorithms to handle
broken conformity of the grid during modification, more attention to the
problem is needed.
Added visual studio debugger helpers.
Fixed several issues with openmp support.
Added openmp parallelization of BiCGStab(L) solver.
Fixed issues that files overwritten with MPI_File* functionality may
contain previous information.
Fixed a bug in OctreeCutcell, added another example for it.
Fixed a bug in collective operations in mesh class.

Don't write markers in internal mesh format.
Fixed bug in EndModification.

Finished documentation for class Cell.
Added algorithm for 2d case of Cell::Inside.
Allowed to change mesh for reference_array class.

Quick and dirty fix for #3

Various fixes

Cleaned bugs; added features.

Huge update involving update of underlying data representation and
elements management. Different interaction with iterators. New
ElementSet representation.  Some annotation for documentation is added.
New data structures. Examples require update. (check
examples/CMakeLists.txt)

Replacing dereference of zero'th element by data();
Fixed issues in GridGen that prevented compilation by microsoft visual
studio compiler;
Fixed small bug introduced by previous commit.

Moving connections, markers, geometric type, sparse data from Storage
class to TagManager class by using standard handling of mesh data.

Fix few compile warnings and a small bug in Element::Mean.

Retrieval of elements by markers;
Introduced options for loading of files;
Fixed issues saving vtk format when not all topological tests are
active;
Introduced Connect / Disconnect functions for manipulations with mesh;
DrawGrid example can now visualize array of entered cells/faces for
debug purposes;
OldDrawGrid example demonstrates fast interactive mesh slicing and
onscreen element picking.
