Simple implementation of AbstractFeVolumeIntegralAssembler which provides mass matrices for a given mesh, multiplied by a scale factor if required. In other words, the matrix
M_{ij} = k integral_{domain} phi_i(x) phi_j(x) dV
where phi_i is the i-th (linear) basis function and k the scale factor (constant throughout the mesh).

Constructor.
pMesh | the mesh |
scaleFactor | the factor with which the multiply the mass matrix. Defaults to 1.0 |

Implemented ComputeMatrixTerm(), defined in AbstractFeVolumeIntegralAssembler. See documentation in that class.
rPhi | The basis functions, rPhi(i) = phi_i, i=1..numBases. |
rGradPhi | Basis gradients, rGradPhi(i,j) = d(phi_j)/d(X_i). |
rX | The point in space. |
rU | The unknown as a vector, u(i) = u_i. |
rGradU | The gradient of the unknown as a matrix, rGradU(i,j) = d(u_i)/d(X_j). |
pElement | Pointer to the element. |
