Add audio support using SFML

See merge request !209

Replace the ssh links for some dependencies with https ones

See merge request !219

This will not mandate the users that checkout the code to set up ssh

Add audio testing examples in sandbox. Add resources to the data folder

A cmake option to enable audio is provided which is not enabled by default.
Only audio module of the SFML is build using the cmake options.

Vulkan renderer

See merge request !111

ENH: Print the user controls

See merge request !218

Print the user controls at the start
of the simulation.

Add UPS print utilities

See merge request !217

Adds option to reset the dynamic objects of the scene

See merge request !196

The reset doesn't work for NeoHookean PBD constraints but works
for other types of constraints. This is added to issue tracker.

Using StVK type FEM constraint in PBDVolume() example

Some format enforcements by Uncrustify

The kinematic state of the objects are reset to the initial state stored in 'm_initialState'

Rename source code folder from 'Base' to 'Source'

See merge request !216

Minor clean/refactoring of core classes

See merge request !215

1. Enables correct winding of the surface
triangles of the surface mesh extracted from the
tetrahedral mesh
2. Adds render material for the surface mesh
3. Change the default mesh that is loaded in the sandbox example

Currently, if all the damping coefficients are zero,
the initialization is stopped in between which is not
intended.

Modifications are made to continue initialization of
the rest of the FE mode if all damping coefficients are zero.

The inverse mass vector which is used to
enforce fixed constraints are reinitialized
after properly set which can cause most of the
nodes to be fixed (bug).

Enforces const correctness

1. Enforces const correctness
2. Adds move constructors

1. Enforces const correctness
2. Adds move constructors
3. Adds comments

Adds option to start the simulation manager with
the simulation either in RUNNING or PAUSED mode
and the viewer in DEBUG or SIMULATION mode.

Other changes:
1. enforce const correctness
2. add comments to the member functions
3. add overload function to retrieve scene manager by scene object
4. rename 'current' scene to 'active' scene
