Issue #41: Out of date examples.

The micro and macro controller examples are out of date by referencing config files in individual folder/config.file(s). This pull requests fixes both examples by pointing to the Common.php config file and added in the methods in which code needs to be written within to clarify where in the file to make changes.
I was discussing the same in the above. I have a feeling this modifyWebDispacther() and modifyWebRouter will be confusing for people new to aura.
