* @short Represents a model described in the BUGS language
*
* ParseTree objects are used to represent a BUGS model description
* after it has been processed by the parser.
*
* ParseTree objects form a tree structure in which the parameters of
* the node are its children. In order to enforce a valid tree
* structure certain restrictions are placed on the setParameters
* function.
*
* ParseTree objects are designed to be dynamically allocated. A
* ParseTree object takes ownership of its parameters and deletes them
* when it is deleted. Hence you only need to delete the top-level
* ParseTree object.
