deprecate arithmetic operators for ranges; eliminate use in Octave
* Range.h, Range.cc: Deprecate unary -, binary +, -, *, and /
operators for Range objects.
(Range::m_cache): Delete mutable data member. Remove all uses.
(Range::clear_cache): Delete function and all uses.
* op-range.cc: Eliminate special arithmetic operators for ranges. All
computations will now be performed as arrays. Eliminate special
concatenation functions.
