%    SETOPT can modify a default option vector with user specified options.
%
%    Input: 
%       opt_par : Users desired option vector
%       default : Program default option vector
%
%    Output: 
%       option : New option vector
%
%    Example:
%       opt_par = [1 2 3 4];
%       default = [1 1 1 1];
%       option = setopt(opt_par,default)
%       option = 1     2     3     4
