I made a few changes to stereo_corr to load an existing D_sub file if found, instead of creating a new D_sub by default. This allows the user to create their own D_sub file to seed stereo_corr, or clean up an existing D_sub before re-running stereo_crr.
build_vw_asp: added build script
build_vw_asp: fix git commands and number of processors
build_vw_asp: specify gcc4.7
build_vw_asp: minor changes
build_vw_asp: laszip fix
Executable stereo_corr does this by default now. It will not recreate a D_sub if one already exists.
