Subject [07/10] git commit: [flex-falcon] [refs/heads/develop] - Added emission of 'org.apache.flex.utils.Language' methods and supporting code.
Date Fri, 01 Nov 2013 11:33:20 GMT
Added emission of 'org.apache.flex.utils.Language' methods and supporting code.

Supported methods are 'as', 'int', 'is', 'trace' (partial) and 'uint'.

In order for 'is' to work, all classes implementing, and all interfaces extending, interfaces
get a (static) constant added to their 'footer': an Array of references to the implemented/extended
interfaces.
