/** \brief Structure describing all nets in an FPGA
 *
 * This structure is an N-ary tree. The first-level nodes are the
 * different nets; then from then on each GNode contains a pointer to
 * some (pip + site) reference, and links between GNodes reflect copper
 * wiring inside the chip (ie, wiring which is not part of the explicit
 * description that we get from the bitstream, but which is contained in
 * the physical chip layout).
