Write documentation objects to `./man`

[halpo]

To fill the promise of creating a full documentation solution there needs to be a function that creates the Rd files from all the objects in a package.

This will have to

1. Have the objects loaded.
2. Have all example blocks associated.
3. Have a way to combine documentation objects into the same file for output.
4. Be able to infer the filename.

Then run the format_Rd function for each object to create the resulting files.
