    version 1.0 18.01.2006 by Frode Rustoy

Three functions to select, deselect or invert selction in one or more sets of checboxes in a form

All three functions takes the same two parameters:

    boxName: one or more name used on one set. If more then one set separate with comma
    theForm: the form containing the checboxes AND the buttons to trigger the functions

SAMPLE:

<button type="button" onclick="PORTFOLIO.checkAllCheckboxes('check_container,check_object',this.form);">
Select all
</button>

In the above sample all checboxes named check_container or check_object in the same form that
also contain the button itself should be selected.
