Examples of ptolemy.data.expr.StringParameter

ptolemy.data.expr.StringParameter
This subclass of Parameter is almost identical to Parameter except that it sets itself to string mode in the constructor. In addition, there is a convenience method, stringValue(), that is equivalent to the following expression:
```
 ((StringToken)this.getToken()).stringValue() 
```
This subclass is provided mainly so that string-mode parameters can be specified in MoML. Consequently, the only constructor provided is the one needed by MoML.
