Close an open file.
This function closes access to a file that has been previously opened with
the open function.
Strictly speaking, it is not necessary to close files, since progeCAD does
that when it exits. However, for good housekeeping, it's a good idea to use
the close function.
The file-descriptor argument represents the file descriptor assigned when the file was opened using the open function. The file descriptor remains after the file is closed but is not valid.
NOTE The file-descriptor must be assigned to a symbol using close function as the file-descriptor.
