*
* Creates a new class, named by <i>aString</i>, containing accessor
* methods for the given symbols. If the name <i>aString</i> is
* omitted, an anonymous structure class will be created. Otherwise,
* the name of this struct will appear as a constant in class

* structure. The number of actual parameters must be
* less than or equal to the number of attributes defined for this
* class; unset parameters default to <code>nil</code>. Passing too many
* parameters will raise an <code>ArgumentError</code>.
