Init the variable system for simulations of Heat equation.
The variable system describes, which variables are to be used and how they are organized in the memory. The first few variables up to the sys_mark are those, describing the state, and thus describe the output for regular restart files. Here these are the conservative variables density, momentum and energy. After the mark, there are additional values described that can be deduced from the state variables.
