stereo_rfne: Print messages just once
all: Drop RMAX software

This software was used only for one project, the mapping of Marscape
via the RMAX helicopter. Neither the RMAX hardware or Marscape exist
anymore. We still have the dataset file ... but if anyone was
interested, it could be processed with our generic PinholeSession.
stereo_mpi.in: Minor usage fix
Add Ben's sparse disparity Python code
sparse_disp: add --processes option
Changes to est_ep_vec in sparse_disp.in to use only the central 68% of the disparities in estimating the epipolar vector.  Fixed an earlier bug that Oleg found, by replacing > and < with >= and <=, respectively.
add recalc_disp chack to sparse_disp

When the refinement loop finished early, all_pts and nbhd_range were inconsistent.  If this happens, recalculate both.
sparse_disp: Use python >= 2.6
DemDisparity: Allow dem_accuracy == 0
Rename DEM acuracy to DEM error. Add documentation
Minor doc work
point2dem: Make default K=1

Projections error out if K is zero. Most people want 1.
stereo_rfne: Bug fix: My upcoming testsuite will help eliminate such glitches
sparse_disp: Coarser level parallism
sparse_disp: Use ASP conventions for input
stereo_corr: Tell user when using cached disp file
LocalHomography: Robustness, increase local box on failure
stereo.cc: Must provide cameras for RPC, this is not a cube!
sparse_disp: Put in Bens bugfix and cleanup
build_vw_asp: added build script
