Each integrator gets its own LocalMatrixContainer object, with information on term grouping specific to the terms handled by that integrator. To conserve memory, all LocalMatrixContainer objects share a common pool of data vectors. After insertion, the common pool can be reused in the next integration. It is the responsibility of the integrator to zero out and resize each data vector as needed.
To leave the system as flexible as possible, this class does not specify anything about the ordering of elements in the matrix. It is the responsibility of the integrator and inserter classes to use a consistent ordering. Different integrator-inserter combinations may well use different orderings.
It is often the case that several terms in a PDE will yield local matrices that have the same values, perhaps differing by a constant, but which are associated with different test and unknown functions. For this reason, each batch of local matrix values has associated with it arrays of (test, unk) pairs and coefficients.
