example

split a-type-of-length-6 to sub-type-of-4 and sub-type-of-2; disallow-padding AND disallow-incomplete-type

        #nv_cli_unsum_int -c 6 -t U4 4 U2 2  

	{
	  capacity: 6,
	  subtyped: { 
        	 U4_U2:    [ 4, 2 ], 
     		 U2_U4:    [ 2, 4 ], 
		 U2_U2_U2: [ 2, 2, 2 ] 
	  }
	}

split a-type-of-length-6 to sub-type-of-4 and sub-type-of-2; allow-padding BUT disallow-incomplete-type
