e22ed9852a bugfixes and improvements
Bugfixes:

Simplify and correct one derivation of a second derivative of energy function.

Clear dynamic variables for static shapes

Invalidate contact for a particle when its type switches from dynamic to static

Improvements:

Allow user to apply force to a particle

Allow user to displace a particle

Compute kinetic energy

Store the mass of each particle, not only its inverse. It can improve performance because the solver needs the masses most of the time for computations

Add some code to find shared and non-shared edges. These algorithms don't work for non-manifold meshes

Remove some unecessary temporaries decreasing code readability
