40debf6a5f Add tentative Peaceman well support. 
Callers may pass NULLs in absence of wells in any given model.  This
implementation assembles an equation for each well, irrespective of
well control type (BHP or RATE), and assumes that productivity indices
and perforation pressure drops account for multiphase effects.

2eb4a6f4a2 Only maintain number of rows in CSR matrix. 
We will generate square matrices only in the foreseeable future and
there is no need to maintain the number of columns (the 'n' member)
separately.  Update all users accordingly.

Based on component formulas derived from the ->pimpl->masstrans_f and
->pimpl->gravtrans_f quantities.

08e2e9c1a3 Only compute face pressure values if explicitly requested. 
Following cset ba5d27f90d7a there is no need to compute the interface
pressure values after every linear solve.  Re-factor
cfs_tpfa_press_flux() to only compute cell pressures and interface
fluxes, and move interface pressure value computation to cfs_tpfa_fpress().

c26d494696 Complete transition to all-int topology in CSRMatrix structure. 
Having a 'MAT_SIZE_T' that is sometimes an int and sometimes an
mwSignedIndex is asking for trouble.  The practical impact for OPM is
low, though, as this issue affects only the MEX interface.

744a08e513 Promote MEX fluid matrix impl. to official status. 
Specifically, move the evaluation of cell transmissibilities into
cfs_tpfa module (from original MEX implementation), and create a new
structure, 'struct compr_quantities', to hold the 'RB^{-1}' data and
(upwind) phase mobilities &c.

0ffaafc9ee Upwind mobility strategy for computing flux/if-pressures. 
Derive interface pressure values from fluxes rather than the other way
around.

64cf39691e Compute real Darcy flux in cfs_tpfa_press_flux(). 
The previous edition made the grave mistake of summing the mass fluxes
per face.  This does not make sense.

552bfd5f00 Add flux and face-pressure computations. 
Specifically, introduce utilities compute_fpress() and
compute_flux().  The former is needed to implement the latter across
external boundary faces.  Moreover, interface pressure values are
needed to evaluate fluid properties on faces (specifically R/B).

Add small gateway routine, cfs_tpfa_fpress(), to allow callers to
recover interface pressure values.  Re-implement cfs_tpfa_press_flux()
in terms of compute_fpress() and compute_flux().

Also, add fields 'fpress' and 'fpaccum' to struct cfs_tpfa_impl.

dba90f41bd Tentatively add boundary condition support. 
We currently handle only Dirichlet (pressure) BC's, and the feature is
largely untested.  More work remaining.

650de8a127 Correct silly mistake in defining hface phase contribs.

different contribution for each face for each cell...

99383e8f02 Move compressible support utilities to cfs_tpfa module. 
We may wish to generalise this part into real utility functions but
for now, leave the functionality where it is most directly needed.
Rename the functions to highlight relationship to compr. tpfa.
