Integrating LocationIQ with AIMMS

This AIMMS project illustrates the use of the LocationIQ AIMMS Library:

1. It provides an alternative to the AIMMS function GeoFindCoordinates. The argument names are the same, and the return value is the same.
   1. Copy the library to your own application.
   2. Get an access token from LocationIQ
   3. Replace calls to GeoFindCoordinates by calls to liq::pr_GeoFindCoordinates.
2. It illustrates using the AIMMS DEX client library including its error handling.
