Remarks
A bidirectional range. Allows you to read or remove the first or last element in a range.
The bidirectional range interface is useful for supporting data structures such as doubly-linked lists that have a front and a back but no efficient access to the middle.
Please see IFRange<T> for general documentation about ranges.
