Pow operator

[dakk]

Implement the ast.Pow operator () between a variable and an integer constant. Since a n == a a ... * a, we implement this operator with a rewriting rule in ast2ast.

The rewriting rule should be placed in the class AstRewriter (https://github.com/dakk/qlasskit/blob/master/qlasskit/ast2ast.py#L137), overriding the method visit_Pow, and rewriting the pow as multiplications.

• Check that n is an ast.Constant, positive integer
• If overriding visit_Pow won't work, override visit_BinOp instead and check if the expression is a ast.Pow

@Youngcius according to rules, an Issue is assigned to a contributor if contributor's PR gets successfully approved by the maintainer. I'm sorry for the confusion.

@tomv42 thank you for the contribution, I merged the pull request after I made just a tiny edit, by using Qtype.fill instead of pad_operand (https://github.com/dakk/qlasskit/commit/d8b299efc40205cc1f6a75a39b9cc192fcc092d0).

Please comment this issue so I'm able to assign it to you.
