Metacat

Added a function to strip out the whitespace that was around the bounding
coordinates retrieved from metacat, and also now writing the full set of
bounding coordiantes (east,west,south,north).

Changed the headers.

Filed used my the Metacat Spatial Option. Generally these files represent
the portion of the spatial option that harvests spatial elements from a
Metacat, and stores the elements as a shapefile on the file system. This
option, at this point, is pretty much independent of the metacat application....
