Updated ignore list.
Removed cartodb and rCharts since they don't exist on CRAN.

CartoDB Is here: https://github.com/Vizzuality/cartodb-r and I don't think it will be on CRAN.
Removing functions we can't include because imports not on CRAN.
Removing non-existent exports
Updating documentation and code formatting
Removed old documentation.
Added my local notes to ignore list
Additional clean up (correct imports, fixed examples) to allow checks to pass.
Added unit test. Addresses #28

Test coverage is not comprehensive at this time but covers all the major functionality. Utility functions are not tested so it would be great to add it in at some point.
Final conflicts resolved, all checks and tests pass.
