Overhaul Range object in liboctave. * Range.h (Range (b, l), Range (b, l, i)): For 2- or 3-element form of constructor, set internal rng_limit equal to actual limit of range object. * Range.h (set_base, set_limit, set_inc): Change to prototypes only. Implementation moved to Range.cc * Range.cc (matrix_value): Return rng_base for first element, rng_limit for last element. * Range.cc (checkelem, elem, index): Simplify functions by returning rng_limit for last element. * Range.cc (sort_internal (bool), sort_internal (Array<octave_idx_t>, bool)): Simplify functions by simply swapping rng_base and rng_limit when sorting a range in the opposite direction. * Range.cc (operator <<): Simplify function by returning rng_limit for last element. * Range.cc (operator >>): Fix input stream operator so a correctly sync'ed range object is created with the correct rng_limit and rng_numel. * Range.cc (set_base, set_inc): Update rng_numel by calling numel_internal () after changing base or increment so that range object is correctly in sync with itself. Clip rng_limit to true limit of data after base or inc has been set. * Range.h (set_limit): Update rng_numel after changing internal rng_limit. Clip rng_limit to actual limit of range object.
