all: Relicense for 2013
stereo_tri: Explicitly tell to cache instead of implicitly

We were doing it implicitly by calling reverse_bbox. However the very
calculation of reverse bbox is pretty expensive.
docs: Update acknowledgements and authors

Several of the people mentioned in these pages have PhDs. We should
recognize their achievement.
docs: Remove excessive examples
docs: Drop knowledge of SURF

We've moved well past the need for this.
docs: Update the tutorial
stereo_tri: Make compile without ISIS
RPC: Revert 04f0645

Returning negative numbers is a bad idea as it causes raster bounding
boxes to always include that pixel. This makes raster buffer inside
TransformView really large and was causing David's memory problems.

Oleg didn't catch on to this because when he wrote that code he was
using RPCMapTransform with the Convex option turned on. (Something I
did).
all: This is ASP 2.2
Doc: + dg_mosaic, stereo_mpi, dem_geoid, point2las, more on DG
Minor wording cleanup of dg_mosaic and stereo_mpi
Minor doc cleanup
Spell
Doc: More geoid/areoid and cleanup
stereo_tri: dgmaprpc: Have caching happen correctly

I goofed and my prior idea of pre-caching the point cloud wasn't
working becuase I didn't use the correct type.
RPC: Must interpolate if at a non-integer location
examples: Recommend affineepipolar over homography
point2las: API changed, was failing for .laz
point2las: Final fix, works w/ and w/o compression
TestStereoSessionDGMapRPC: Clarity
