Initial Support for PM::WebScreen
Only go forward or back if we can.
Support opening links in chrome if installed on the users' devices. Add pod 'OpenInChrome' to the rakefile to enable this as the default behavior.

  Simplify the code for adding annotations.
  Better params handling for initializing an annotation.

  Convert all CLLocationCoordinate2DMake calls to CLLocationCoordinate2D.new
  Unit & Functional tests for MapScreen. All tests passing.

  Get and set center position of the map.
  Decided against the metaprogramming for now.

  Why was this .DS_Store file here?
  Metaprogramming FTW!

  First attempt at providing a more "table_data" like DSL for the mapkit annotations.
  Fixed but in adding multiple annotations.
  Better defaults handling in the MapScreenAnnotation.
  Handle annotations, regions and zooming to coordinates.
  Support annotations.
