00060  * NB I don't think that this class needs to be templated over PROBLEM_DIM,
00061  *  since even when working with Bidomain we only integrate one thing at once,
00062  *  and hence still need to call AbstractFunctionalCalculator<ELEMENT_DIM, SPACE_DIM, 1>.
00063  *  See PostProcessingWriter.cpp line ~141. The fact that it is only explicitly
00064  *  instantiated (at the bottom of the cpp) for cases with 1, would agree with this.
00065  *
00066  *  But at the same time it probably isn't worth breaking users' code by changing it.
00067  *  Might also make it easier to copy and paste for any new class that does a
00068  *  fancier integral with more quantities.
