GeoEye->OSGEO merges

[dburken]

Merges from GeoEye to OSGEO ossim baseline.

Multiple updates to epsg factory code(Oscar Kramer).

Updates to ossimCoarseGridModel and ossimDblGrid(Oscar Kramer). From trac: Commit associated with improvements to ossimCoarseGridModel and associated code:

• Added native extrapolation capability in ossimDblGrid
• Added numerical domain consideration in ossimDblGrid for interpolation and extrapolation to recognize longitude wrap.
• Enhanced ossimDblGrid::filter()
• Added extrapolate method override in ossimCoarseGridModel to use new ossimDblGrid extrapolator.
• Added damping in ossimSensorModel::worldToLineSample() when oscillation detected for better convergence with noisy data.

Fixed ossimMapProjection::operator== checking datum address instead of object. Update ossimUtmProjection::operator== to check it's stuff before call map projection. Added operator!= to datum and ellipse code. Fixed ellipse operator== not checking theA param. Added open to tiff world.

Multiple updates to fgdc parser to handle data from National Agriculture Imagery Program (NAIP). Added ossimKakaduJp2Reader::getMetadataImageGeometry to pick up external geom from fgdc xml doc and j2w file if present.

Added ossimImageGeometry::getCornerGpts

Added ossimTiffWorld::open. ossimTiffWorld, math redo (Oscar Kramer)

Added epsg code to ossimEquDistCylProjection.
