=======================================================================================================================
DONE FOR THIS RELEASE
=======================================================================================================================
Fix for latest WME update
=======================================================================================================================
Bug fixes - MUST BE CLEARED BEFORE RELEASE
=======================================================================================================================
=======================================================================================================================
Things to be checked
=======================================================================================================================
Correct generation of name data from PC tool, and correct handling of bounding boxes which are defined in the
adjacent data block but which overlap into the one the mouse pointer co-ords are currently within
=======================================================================================================================
Proposed functionality
=======================================================================================================================
Mark on map where the OS city names are located
Restrict city name uniqueness testing to within each county rather than country-wide
Note: remember that the OS data uses London boroughs whereas Waze uses Greater London...
=======================================================================================================================
New functionality in progress
=======================================================================================================================
