Current version of AMG uses ILU for relaxation, however it is not stable when schur matrix becames more denser. For example it is not stable for -e paramenter is more 400 in 2D for convection problem

This commit cleans up the incompressible solver and adds a DarcyFlux solver in model module. 
Some documentation for both classes has been added.
The convection code is only linear at the moment.
