FormalArgument

java.lang.Object
- org.stringtemplate.v4.compiler.FormalArgument

```
public class FormalArgument
extends java.lang.Object
```
Represents the name of a formal argument defined in a template:
```
  test(a,b,x=defaultvalue) ::= "<a> <n> <x>"
 
```
Each template has a set of these formal arguments or sets CompiledST.hasFormalArgs to false (indicating that no arguments were specified such as when we create a template with new ST(...)).
Note: originally, I tracked cardinality as well as the name of an attribute. I'm leaving the code here as I suspect something may come of it later. Currently, though, cardinality is not used.
