* range.c (range_step): iteration done using "+" if elements are

  Numeric.  Otherwise using "succ".

* range.c (range_each): iteration done using "succ".  If the
  elements does not respond to "succ", raise TypeError.  As a
  result, all Enumerable methods, e.g. collect, require elements
  to respond to "succ'.

* range.c (range_member): comparison done using "each", if
  elements are non-Numeric or no-"succ" objects.  Otherwise
  compare using "<=>".

* range.c (Init_Range): remove "size" and "length".
