HeatConduction Physics syntax

The [HeatConduction] block is a sub-block of the [Physics] block. HeatConductionPhysicsBase-derived classes, such as HeatConductionCG can be created, nested under the relevant discretization sub-block.

For example, a continuous Galerkin finite element discretization of the heat conduction equation can be created inside the Physics/HeatConduction/FiniteElement block.
