/** \brief Maps the vertices of the subcell parametrization domain to that subcell.
Parametrization tests check if the vertices of the parametrization domain are properly
mapped to vertices of the resepective reference subcell. Because the parametrization map
is a polynomial whose degree depends on the number of vertices, if all vertices are
mapped correctly this is sufficient to assert that the parametrization map is correct.
To test reference cells with two different kinds of faces, there are two argument slots
to pass vertices of parametrization domains "A" and "B". When testing edges always pass
the same argument because edges have the same parametrization domain [-1,1] (1-cube)
\param errorFlag [out] - counts number of errors
\param parentCell [in] - topology of the reference cell whose 1 and 2-subcells are parametrized
\param subcParamVert_A [in] - vertex coordinates of parametrization domain "A" (2-simplex for faces)
\param subcParamVert_A [in] - vertex coordinates of parametrization domain "B" (2-cube for faces)
\param subcDim [in] - dimension of the subcells whose parametrizations are tested
\param outStream [in] - output stream to write
