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.

BUG: Fixed bug with PBD collision

See merge request !156

ENH: use latest version of Eigen

Closes #118

See merge request !157

- Velocity of particles should be updated only after collision being
  resolved.
- Rename from integrateVelocity() to updateVelocity() for pbdObject and
  pbdModel.

ENH: implemented spatial hashing and added an abstract class

See merge request !147

BUG: Fix point plane cd

See merge request !154

ENH: Add capsule geometry, capsule-mesh collision and rendering

See merge request !149

Currently VTK doesn't support capsule actor.
vtkCapsuleSource class originally authored by
Johan Andruejol <johan.andruejol@kitware.com>
was modified and used. The source of vtkCapsuleSource
class is placed in the imstk source for the moment.
This has to be migrated to vtk proper in the future.

Adds capsule-point cloud collision detection.
First the each point in mesh is checked against
the bounding sphere of the capsule. If inside,
the closest point is found on the line joining
the two apexes of the capsule. If the point
is inside the bounding sphere then the closest
point should be inside the capsule. If the distance
between the closest point and the mesh point is less
than radius of the hemispheres of the capsule, the
collision is registered.

BUG: Fix mismatch of Libusb file hash during download
