Examples of RegexSimpleParser

uk.co.badgersinfoil.metaas.impl.parser.regexsimple.RegexSimpleParser
Provides a simple scanner that can recognose the extent of a regular expression within the surrounding actionscript program, without parsing it 'fully'. This should be the simplest possible handling that will allow the 'outer' actionscript grammar to find the end of the regular expression literal, anc continue parsing the rest of the code.
