8ffb83467f Implement facility for passing external solver software to resolve 
the local systems of linear equations.

  Implement utility for deriving symmetrised (projected) basis
  function flux values from a back-substitution process following a
  local system solve.

203890ed69 CSR start pointer definition loop runs from 1 to nbins+1 inclusive. 
Fix off-by-one in define_csr_sparsity...

  Replace useless table of number of *internal* fine-scale faces per
  block with the marginally more useful total number of fine-scale
  faces per block.  Otherwise we were allocating too little space for
  the local systems.

6126c0b4ea Add a routine for allocating a CSR matrix with known number of rows 
and non-zeros.  Note that this routine is for allocation only.
  Caller must create and manage sparsity structure if this is being
  used in a global assembly process.

  This routine finds utility in MsMFEM BF construction.

1982240882 - We hereby nominate indexing by 2 in pimpl->cwells as one of the 
worst decisions ever.  Fix yet another fall-out from this decision
    in the global assembly of well contributions.  Possibly the final
    *extant* of these, but further such changes will likely be
    introduced whenever we make a change.

    Revision needed.

  - Use correct sign when assembling total rate constraints.  Target
    values (currently) denote *injection* fluxes.

53b9546364 The global assembly of well contributions requires local-to-global 
mappings pertinent to the actual cell/well in question, not the
  first cell/well pair.

  With this change (and -r5370), we are now able to form (and solve)
  the complete well configuration on the IO Centre model.  The
  solution, however, leaves a lot to be desired.  Further
  investigation is required.

52ce1c33cf Implement back-substitution support for wells. The test script 
(test_mex_ifsh) appears to yield satisfactory results, but (much)
  more testing is needed.

91fe03a9d0 Declare headers (in a suitable $(includedir)), extra Autoconf macro 
directory, and disable Dune-specific Automake include rule.

  Rely on Dune users to re-enable the latter (but not to expose the rest
  of the world to that enabling).

55b821eded Fix two blatantly ignorant formulation errors in the Schur reduction 
implementation of well contributions:

    - First, we were neglecting the connection-to-block strength
      reduction factor 'L' in the 'w2r' term.  This error was
      compounded by even implementing the wrong *sign* of the term.

    - Secondly, the local well-connection number is hardly ever two,
      so index 'wdp' by 'w' rather than '2'.

  Pointy hat: bska.

283513a342 - Correct an embarrassing loop-index error. We were looping over 
'w', but increasing 'i'.

  - Adopt changes to 'cwells' convention (stores both well number
    (in 2*pos+0) and inverse perf index (in 2*pos+1)).

8cf595df43 Don't bother checking for NULL-ness in dtor. Ifsh_destroy() already 
does this, and it is okay to rely on this fact.
