 Tracking Locations
 ==================
 
    Though grammar rules and semantic actions are enough to write a fully
 functional parser, it can be useful to process some additional
 information, especially symbol locations.
 
    The way locations are handled is defined by providing a data type,
 and actions to take when rules are matched.

* Actions and Locations       Using locations in actions.
* Location Default Action     Defining a general way to compute locations.
