+	dim_vector::str, dim_vector::num_ones, dim_vector::safe_numel, 
+	dim_vector::squeeze, dim_vector::concat, dim_vector::redim):
+	Move bodies to dim_vector.cc. 
+	(dim_vector::concat): Rewrite.
+	* Array.cc (Array::cat): Fix dim_vector concatenation. Don't use 0x0
+	as neutral element, because it isn't with dim > 1.
