Diffusion module

• Current State
• ToDos

This is the according repository to the diffusion module we discussed earlier. With this readme I will document all my steps I've done and will do.

Current State

• 1D diffusion is possible by setting bc at left/right end by hand or use the default value (Neumann with gradient 0)
• Always set concentrations/diffusion coefficients by using std::vector
• simple datastructure, which is currently just a class called BTCSDiffusion

ToDos

• keep sparse matrix in memory
• allow different boundary conditions at the ends and also inside the grid
• implement 2D diffusion
