The 3ds file loading and attachment  of VAO for the tangents
for 3DS file are working fine now.

The tangents transfer to the shaders need to be checked.

-Has some general fixes(wrong types and stuff).
-Fixes the in-house openGL renderer.
-Fixes Oculus support.
-Moved around some stuff in the renderers.
-Generalized RenderCube to be an example scene so
all the other cube based examples can use common code.

for surface meshes. This was causing crashes when trying to
render. Clean the attachSurfaceMesh routines and add two more
routines: readWeigths() and generateWeigths().

delegates.
The way render delegates need a bit of work.

Automating the way renderers are loaded.

Fix broken tests.
The renderCube example is broken now. Submitting patch soon.

Revert to build command in the Superbuild so that parallel
build work again.

Clean up and add static scene delegate.

Documenting IO. Change name for IO delegates to match file name.

Capture by value in the IO delegator so that it remembers about the
delegate file name and IO pointer.

Fixing examples so they use the new IOs and renderer.

Add tests to IO. Move variables, types and implementation
of utility methods to IOMeshDelagates base class.

Commented out the VegaVoumetricMesh test until after I debug the meshIO.

Add reset function to base mash

in order to reset vertices to their original position.
Strip const from read function in the IOMeshDelegate and childs.
Move some utility functions to IOMeshDelegate.

Clean up as well.

This data mapper allows you to map external data into the
vtkDataArray.
This in turn allows you to interface with vtk without
repacking the simulatordata.

Clean up and implement a pimpl VtkRenderer to hide
redering implementation.

Replace core::StdVector3d with std::vector<core::Vec3d>

because eigen 3d vector array is aligned
by default so no special allocator is needed. See core::StdVector3d
for more details.

Also renmamed many unseen sm* class names.
