/**
* Localization System
*
* This framework handles localization. Localization in new ISSO
* applications is done through this framework. Nearly all strings
* are passed to the string function, which looks up the string in
* a .strings.xml file during runtime. Before release, a C tool
* creates the .strings.xml file for translators. Common strings
* can be accessed through the get lex function which calls a string
* based on unique identifier; this is useful for commonly used strings.
