#include <Wall.h>
Represents a wall between between two ReactorBase objects.
Walls can move (changing the volume of the adjacent reactors) and allow heat transfer between reactors.

Rate of volume change (m^3/s) for the adjacent reactors.
The volume rate of change is given by
\[ \dot V = K A (P_{left} - P_{right}) + F(t) \]
where K is the specified expansion rate coefficient, A is the wall area, and F(t) is a specified function of time. Positive values for vdot correspond to increases in the volume of reactor on left, and decreases in the volume of the reactor on the right.
Reimplemented from WallBase.
