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