function c = cdv(varargin)
% CDV - Constructor for the class cdv, a sub class of the gen class.
% The constructor is called as follows:
%
% cdv('name',low_limit,high_limit,bits) 
% 'name' - the name that identify the variable
% low_limit - the lower limit for the variable
% high_limit - the upper limit for the variable
% bits - the number of bits used to code the variable
%
% if the constructor is called without any arguments it returns an
% empty variable.
%
