Virtual coupling object

See merge request !150

Allow access to collision detection and collidion handling algorithms.

Forces were wrongfully applied by the controllers onto the external
devices before the forces were computed.

Module callbacks

See merge request !165

The current integration of UPS within the module class did not allow
to display the UPS value in any easy and standardized way.

This commits simplifies the Module class by removing its dependency to
the UPSCounter class, and shows how to easily query the UPS using the
callback mechanism on any module (here: sceneManager for pbd physics and
fem physics examples).

Allows to set up custom behaviors in all subclasses of the Module class,
at:
- prior to initialization
- after initialization
- prior to update
- after update
- prior to clean up
- after clean up

Improve the testTwoFalcons example in Sandbox to quickly illustrate how
to simply setup a logger for a deviceclient using those features.

* Remove camera controller from test since already shown in
testCameraController, to be able to test with just two falcons
* Update some initial geometry and camera positions
* remove imstk namespace since using namespace imstk in sandbox

ENH: Spatial hashing CD

Closes #109

See merge request !155

ENH: New return type of SpatialHashTableSeparateChaining::getPointsInAABB() enables referencing vertices by their IDs. It also causes less constructor and allocation invocations.

Compute collision data for one-sided collision between a plane and a sphere

See merge request !163

ENH: Adds UPS counter utility

See merge request !158

ENH: adding write support for SurfaceMesh via VTKMeshIO

See merge request !161

Adds updates per second (UPS) counter utility.

USAGE:
UPSCounter->setStartPointOfFrame();
...
... (work load of the frame)
...
UPSCounter->setEndPointOfFrame();

// Get the updates per second
UPSCounter->getUPS();

ENH: Migrate iMSTK from my.cdash.org to open.cdash.org

See merge request !162

Migrating to better maintained instance of CDash.

BUG: Fix #122 black analytic objects

Closes #122

See merge request !160

Assimp Importer

See merge request !142

Fix regression introduced in !121 with the use of the fast normals filter
`vtkTriangleMeshPointNormals`. That filter was also applied for surface
meshes with non-triangular cells: cells, sphere, capsule, cube (quads and
not triangles).

Since the issue of non-triangular meshes comes from analytic mesh sources,
the output surface meshes will always be rigid, so their normals will stay
constant and won't need to be recomputed. We can therefore use the filter
`vtkPolyDataNormals`, which is slower but will only need to be called once
of no deformation occurs.
