StrDict::GetVar( int, StrPtr &, StrPtr & )

Return the value of the specified variable, or NULL if not defined.

Class	`StrDict`
Arguments	`int i`	the index of a variable in the `StrDict`
	`StrPtr &var`	the name of the variable at that index, if any
	`StrPtr &val`	the value found at that index, if any

This method is typically used when iterating through a StrDict.

For the most part, all of the GetVar() methods are equivalent.
