    Abc Assembler Tests

    It is possible to write tests using the abc assembler.  The assembler code can be found in /utils/abcasm.  Tests can be found in /test/acceptance/abcasm and end with the .abs extension.  The tests are run using the same script that is used for the actionscript tests.  

    When run, the assembler tests include the abcasm/ file which defines the following functions:

    START(Summary:String):void - Start a new test section described by Summary
    END():void - Test section finished
    COMPARE_STRICTEQ(name:String, expected:*, actual:*):void - Compare the results of a testcase where name is the testcase name
    COMPARE_TYPEERROR(name:String, expected:*, actual:*):void - Special function for comparing TypeErrors (RuntimeErrors) - Will only compare the 
        first 22 chars of expected and actual so that test can be run in Release and ReleaseDebugger configurations.
    COMPARE_NUMBEREQ(name:String, expected:*, actual:*, fractionDigits:int=-1):void - Compare 2 Numbers up to FractionDigits
          This is to be used for high precision numbers that may vary slightly due to platform differences.
