// Declaration of Sequence (numbered list) class.
// Remarks on the current implementation:
//
// 1. Methods First() and Last() added
// 2. The method InsertAt(anIndex) replaces InsertBefore and InsertAfter.
// This method never throws exception "OutOfRange". Its behaviour:
// anIndex <= 1 => equivalent to Prepend()
// anIndex > Length() => equivalent to Append()
// else => equivalent to InsertBefore.
