Useful routines for parsing files.
1.01 (28 March 2001)
Moved 'list_to_string' to CmUtils::Utils as it is more globally useful than just in parsing Cmiss files.
Returns a numeric representation of a string, or 'undef' if the string is not a number. Handles Fortran strings with 'D'.
Returns True (1) if two arrays (passed by reference) are identical (same elements and same number of elements), otherwise returns False (0).
