pc_align: Print centroid of source points
point2dem: Bugfix: Output DEM was mis-aligned compared to input PC
point2dem: Redo algo, use averaging in a circle
InpaintView: Depends on boost::foreach
point2dem: Use gaussian for weights, to antialias
point2dem: Change the way default spacing is computed
point2dem: Bugfix to an earlier bugfix
By default, use parabola subpixel, and affineepipolar

If the user tries to use affineepipolar or homography with map-projected images, the tool will throw an error
parallel_stereo: Print help first thing, other minor
parallel_stereo: Fine-tuning
parallel_stereo: Minor tuneup
point2dem: Doc fine-tuning
Core: Altered InterestPointMatching affine check to allow flipped images
Core: Added some documentation to several classes
Tools: Testing new small blob filter
Tools: Cleaned up new BlobMaskView class
Replaced old ErodeView implementation with new blob masking class
Tools: Added query and pixel crop options to mapproject
