/* xnm_switchLayer
Aim
Minimize and restore the next supirior object with class: "cgroup" using styles: cgroup_closed and cgroup
Assumptions
"cgroup" or "cgroup_closed" are used to format the object which should be toggled.
Styles named "cgroup" and "cgroup_closed" exist int he connected stylsheet.
No Function when using Netscape, because no attribute parentElement is existing.

2010-01-14 MSc: Added my_evetn to enable Firefox to use this function 
NOTE: the Call of this function has to include (this) to enable it for Firefox.
