started to use the eclipse jdt parser
set language level to 1.5
added code style settings
changed the declared visitor methods to the astvisitor structure
removed interface override annotation because of language level 1.5
imported classes will be added to importedClasses map now
removed a debug output
strings are also identified by methodInvocation if argument is an infixexpression  and build just with stringliterals
