//! A framework for computing the global properties of a <br>

//! A point mass is attached to each point. The global <br>
//! mass of the system is the sum of each individual <br>
//! mass. By default, the point mass is equal to 1 and the <br>
//! mass of a system composed of N points is equal to N. <br>
//! Warning <br>
//! A framework of this sort provides functions to handle <br>
//! sets of points easily. But, like any GProp_GProps <br>
//! object, by using the Add function, it can theoretically <br>
//! bring together the computed global properties and <br>
//! those of a system more complex than a set of points . <br>
//! The mass of each point and the density of each <br>
//! component of the composed system must be <br>
//! coherent. Note that this coherence cannot be checked. <br>
//! Nonetheless, you are advised to restrict your use of a <br>
//! GProp_PGProps object to a set of points and to <br>
//! create a GProp_GProps object in order to bring <br>
//! together global properties of different systems. <br>
