We need a page with explanation about the API and links with examples in the handbook.
This includes for example the D6 event coloring taxonomy example.

This page would also need sub-pages with some examples like how to color based on field input for example.

Disable editing for all events

/**
 * Implements hook_fullcalendar_editable().
 */
function custom_module_fullcalendar_editable($entity, $view) {
  // Here I could inspect the entity or the view to make an informed deciscion,
  // but in this case I never want to have the event be editable.
  return FALSE;
}
