Support for ghost annotations

[gustavung]

Ghost code is very nice for making abstract specifications and for verification of complex code. Currently, there seems to be a lack of support for ghost annotations in Tricera. For example, the following example can not be parsed:

//@ ghost int v;

/*@ requires v <= 0;
        requires v >= 1000;
        assigns v;
        ensures v - \old(v) == 1;
*/
void main() {
//@ ghost v = v + 1;
}

This example fails with the following error message:
'Syntax Error, trying to recover and continue parse... for input symbol "" spanning from unknown:1/5(4) to unknown:1/10(9)
(error "Unrecoverable Syntax Error")
Other Error: Unrecoverable Syntax Error'

I agree that this would be a nice addition, thank you for the suggestion. I will look into it, but this might take a while.
