Define the MarsMan documentation

[jvendrell]

Currently, the only documentation of the project is the Middleman's index page, where we can see a list of all the pages styled, and the toolkit. The toolkit contains an example of each one of the components used to create the different pages.

We need to define:

• What kind of documentation does the project need? (toolkit, page examples, how to install, style guidelines, etc.).
• What do we use the toolkit for?
