\n <b>Select from</b> set of fields allows to choose a submesh or an existing
group whose elements of the previously defined type will be added to
the list of elements which will form your group.
-\n <b>Color Number</b> (integer only, ranging from 0 to 9999) - allows to
-assign to the group a certain index, for example, defining boundary
-conditions. This feature introduces a useful element of preprocessing
-in Mesh module. Note that <b>Color number</b> attribute has nothing to do
-with the colors used for the display of the elements of the group.
