iclutil: command-line utility for expanding ICL files

[adamdecaf]

What were you trying to do?
Often it's useful (and better explained) to see ICL files are visual elements expanded from their encoded representation. This can be to label fields and encode them for humans to easier read/understand.

What did you expect to see?
A command-line utility that works on all OS's which more easily displays ICL files for developers to use. We have a tool in the ACH project that expands files out and is popular. A similar tool could be written for ICL files as they follow a similar record/field pattern.
