/*
  Array element referenece or slice view.
  @overload [](dim0,...,dimL)
  @param [Numeric,Range,etc] dim0,...,dimL  Multi-dimensional Index.
  @return [Numeric,NArray::<%=class_name%>] Element object or NArray view.

  --- Returns the element at +dim0+, +dim1+, ... are Numeric indices
  for each dimension, or returns a NArray View as a sliced subarray if
  +dim0+, +dim1+, ... includes other than Numeric index, e.g., Range
  or Array or true.

  @example
      a = Cumo::DFloat.new(4,5).seq
      => Cumo::DFloat#shape=[4,5]
      [[0, 1, 2, 3, 4],
       [5, 6, 7, 8, 9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]]

      a[1,1]
      => 6.0

      a[1..3,1]
      => Cumo::DFloat#shape=[3]
      [6, 11, 16]

      a[1,[1,3,4]]
      => Cumo::DFloat#shape=[3]
      [6, 8, 9]

      a[true,2].fill(99)
      a
      => Cumo::DFloat#shape=[4,5]
      [[0, 1, 99, 3, 4],
       [5, 6, 99, 8, 9],
       [10, 11, 99, 13, 14],
       [15, 16, 99, 18, 19]]
