/**
 * NetworkPort Class
 *
 * There is two parts for a given NetworkPort.
 * The first one, generic, only contains the link to the item, the name and the type of network port.
 * All specific characteristics are owned by the instanciation of the network port : NetworkPortInstantiation.
 * Whenever a port is display (through its form or though item port listing), the NetworkPort class
 * load its instantiation from the instantiation database to display the elements.
 * Moreover, in NetworkPort form, if there is no more than one NetworkName attached to the current
 * port, then, the fields of NetworkName are display. Thus, NetworkPort UI remain similar to 0.83
