Added 2 extra arguments added to "refresh", namely "event" and "user
tag". To the functions which return a figure defined "example.rsc" are
added the same two extra arguments. In the body of the function
handling events can be taken place (see example counter11).

The data type Figure is extended with the property "id". 

A step is made forwards to solve the problems of "extra_figure". 

"trcursor"  is extended with a boolean parameter  "deep".
