Cppcheck clean. No more unitialised member in constructor. Maked constant when possible. Passed by reference when possible. Remaking formating.
Use Von neumann condition.

Equation of state method work.
Creation of file compatible with paraview.
Voisin corrected when asked for begin for a empty particles.
Output of variable.
And first jet d'eau.
Added predictor corrector time integration.
Added viscosity.
Added Variable time step.
And added constant iterator for voisin.
Corrected pressure and viscosity. Now it's more like a fluid.
Removed boost for build no more needed.
Removed analyse no more needed.
Added Documentation. And put some variable in memory instead to calculated them.
Made -wall clean. Added time in output file. Corrected somes bug.
Added turbulence consideration.
Put more reasonable value.
Corrected Kernel. Viscosity now correct.
Added Function to time performance.
Corrected pressure and viscosity. output value of force.
Remove of uneaded function like boundary.
Added documentation.
And poisseuil initial condition.
Added Multithread support.
Added structure for beeman time integration.
