Copies all relations of sourceObj (pointing from or to sourceObj) to this object (including weights).

Useful if you want to make a complete copy of a StoreArray object to make modifications to it, but retain all information on linked objects.

out << "<b>Covariance Matrix</b>: " << HTML::getString(getCovariance5()) << "<br>";
return out.str();

See also: Particle::getInfoHTML() for a more complex example.; HTML for some utility functions.; Use getInfo() to get a raw text version of this output.
