% SETSELECTIONFORPARAM Sets the selection mode of the param object in dependencies of the 'key'
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: Sets the selection mode of the param object in dependencies
%              of the 'key'
%
% CALL:        obj = obj.setSelectionForParam('key', selection);
%              obj = obj.setSelectionForParam(plist('KEY', 'key', 'SELECTION', selection));
%              obj = setSelectionForParam(obj, 'key', selection);
%
% INPUTS:      obj       - can be a vector, matrix, list, or a mix of them.
%              key       - The key which should be changed
%              selection - Selection mode of the parameter
%              pl        - to set the default value of a key with a plist,
%                          please specify only one plist with the key-words
%                          'key' and 'selection'
%
% POSSIBLE VALUES FOR 'selection'
%
%              selection:  1 == paramValue.OPTIONAL
%                          2 == paramValue.SINGLE
%                          3 == paramValue.MULTI
