Add cmake logic so Assimp zlib can be found
in release mode.

Work on Integrate ToolCoupler with ObjectSimulartor
to implement haptics rendering.

Many other cmake improvements.

Fix GLEW/GLU dependency mess.

Set build configuration variables and pass down to to superbuild
external projects.

1. Removing GLEW external project. Glew is now
built with vtk, in order to use it just include
the vtk use file and add the vtkglew library
to the target link directive.

2. BUILD_SHARED_LIBS is now forced to be OFF for
Windows MSVC builds.

Build external shared libs in order to avoid linking issues in windows.

Close #37

Create helper function to read texture coordinates from the OBJ mesh.

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.

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.
