findfile()

Usage:
findfile(filename), filename a CHARACTER scalar



Keywords: files
findfile(filename) returns a path to the requested file, or NULL if the
file cannot be found.  Searching is done based on the paths in
DATAPATHS.  First, findfile() looks for ./filename (the current
directory), then DATAPATHS[1]/filename, DATAPATHS[2]/filename, and
so on.  findfile() returns a path to the first matching file.  Paths
may be relative or absolute depending on DATAPATHS.
