function columnx = column(x)
% FUNCTION:		COLUMN						Part of DPWT Toolbox
%
% SYNOPSIS: 	COLUMNX = COLUMN(x)
%
% DESCRIPTION: 	Make X into a column-vector columnx if 
%				it isn't already. This is for those 
%				programming times when you want to force 
%				a vector to be a column vector. If X is a
%				matrix it is left unchanged 
%				(i.e. COLUMNX = X).
