Changed function name to avoid confusion

This function is used to extract information from the CT_Fire output
database. This change was made to avoid confusion with the CT_Fire tool.
Added option for processing fibers from FIRE in different ways

There are now 3 options for processing FIRE fibers with respect to
boundaries:
1. Process all segments as though there were curvelets.
2. Process fibers (only one segment per fiber is considered, average
fiber angle is assigned to all segments, segments locations are used to
find if fiber is near a boundary).
3. Process fiber ends only (similar to above, just use first and last
portion of the fiber that is close enough to the boundary)
