Improved gridding results. This includes smoother interpolation near faults for all methods and the extension of DIRECT to handle more points without averaging and to honor faults.

Performance improvement in cases involving large grids and sparse data.

Added support for both 32- and 64-bit Windows and Linux platforms.

Increased control over gridding parameters.

New functions for saving, restoring, accessing, and sampling grid information.

Ability to sample gridded results in the context of the original gridded vectors, x and y.

Increased the number of points allowed for the Direct method of gridding from 10,000 to 100,000.
