FOM : Set up solver in FEniCS for the heat equation in a fixed geometry

[emvalbuena]

See Chapters 3 and 5 from the FEniCS tutorial, volume I.

The goal of this task is to touch base with the FEniCS solver with an specific application of the problem we aim to reduce.

• FOM : Install and pass FEniCS tests #7 Set up reproducible environment steps for FEniCS use.
• Plain vanilla equation.
• Introduce physical parameters.
• Wrap into OOC.
