/*
 * NB I don't think that this class needs to be templated over PROBLEM_DIM,
 *  since even when working with Bidomain we only integrate one thing at once,
 *  and hence still need to call AbstractFunctionalCalculator<ELEMENT_DIM, SPACE_DIM, 1>.
 *  See PostProcessingWriter.cpp line ~141. The fact that it is only explicitly
 *  instantiated (at the bottom of the cpp) for cases with 1, would agree with this.
 *
 *  But at the same time it probably isn't worth breaking users' code by changing it.
 *  Might also make it easier to copy and paste for any new class that does a
 *  fancier integral with more quantities.
