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.

e551137f18 Implement partial well support. Schur reduction, assembly and 
system solve *appear* to be okay in rudimentary testing.
  Back-substitution (i.e., cell pressure and interface fluxes) not yet
  aware of wells.

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.

a115ac702b Implement cell-based contributions to global linear systems from 
wells.  In particular, this represents the equivalent of
  hybsys_schur_complement_*() for wells.

883fda040f In preparation of implementing well support, add a new field ('q') 
to struct hybsys, and use this field to store 'src-F2*gpress' per
  cell.  Implement back substitution in terms of hybsys:q, rather than
  computing this value in hybsys_compute_press_flux().

support for function 'mex_compute_coarse_contrib', even if this
  function is entirely for testing/development purposese.

5d0278ba1b Add MEX gateway routine to fully assembled (mimetic/hybrid) 
incompressible flow solver.  Supports boundary conditions (addBC),
  and source terms (addSource).  Single phase only.

  Initial testing is promising (one-phase linear pressure drop across
  cartGrid([250, 250, 10]) solved in about one minute).

fa214b1264 Declare procedure for deriving cell pressures and interface fluxes 
(i.e., projected half-contact fluxes).

9ed3196485 Modify the implementation data: 
- Store effective Binv rather than Schur complement 'S'.
    - Add integer and floating point work arrays (BC handling,
      pressure/flux back-substitution &c.)

  Always allocate integer work array.  Consequently, no need to jump
  through hoops to avoid issues surrounding malloc(0).

  Add simple procedure for imposing prescribed interface pressure
  values (i.e., Dirichlet conditions).

  Correct a few clerical errors (use of unitialised vars &c).

  Assemble global system, but only for reservoir contributions.  Well
  contributions remain.

  Add trivial procedure for deriving cell pressures and interface
  fluxes (projected half-contact fluxes).
