/**
* A test map that contains a grid of each point, line and polygon type that
* is possible. The name of each element is set to be the numeric type (and
* sub-type for points).
*
* This can be used to decode the type_id's.
*
* Instructions for use: If you run this program with the environment
* variables BASE_LAT and BASE_LONG set to something just SW of where you
* are then the map generated will be located near where you are. Otherwise
* the default location is at (51.7, 0.24).
*
* You can then use the find facility of your GPS to
* show the near-by points. When viewing a category the menu key will allow
* you to select finer categories.
