Initial value:

 Plane_Equation (Triplets, verbose)
%
%   [err,Eq] = Plane_Equation (Triplets, [verbose])
%
%Purpose:
%   Determine the equation of the plane passing through three points
%   
%   
%Input Parameters:
%   Triplets is an Nx1 vector of strucutres. Each structure defines a plane
%    .XYZ : is a 3x3 matrix containing the XYZ of each of the three points
%           Each row is a point. ie: XYZ = [0 0 0
