### Static Solver

Description
The StaticSolver contains the algorithm used to update particle positions at each time step. As we are dealing with a Static solver, time (i.e. velocity and acceleration terms) is not taken into account. At each time step, the solver is looking for an equilibrium of the generalized forces at each nodes. Using a static solver can be useful to measure the convergence of several algorithms.
Solving for each point, the static equation amounts to solving a linear system Ax=b. In this scene, the static solver is coupled with an iterative linear solver: the CGLinearSolver, used to solve equation systems.
