A helper method which will extract the n-th generic type from a class node.
@param type the class node from which to pick a generic type
@param gtIndex the index of the generic type to extract
@return the n-th generic type, or {@link org.codehaus.groovy.ast.ClassHelper#OBJECT_TYPE} if it doesn't exist.
