[Cpptool-develop] New refactoring on the wiki

[Baptiste L. <gai...@fr...>]

    I added a few refactoring on the wiki:
    - ReduceTemporaryScope
    - ExtractMethod
    - RenamePrivateField

    ReduceTemporaryScope will definitely be the next to be tackled. It very
useful when facing long method, and we already have all the tool to
implement it.
