 * An arbitrary highlighting interface for Kate.

 * - integration with syntax highlighting:
 *   - eg. a signal for when a new context is created, destroyed, changed
 *   - hopefully make this extension more complimentary to the current syntax highlighting
 * - signal for cursor movement
 * - signal for mouse movement
 * - identical highlight for whole list
 * - signals for view movement
