/**
 * Update the #BOARD with a new netlist.

 * The changes are made to the board are as follows they are not disabled in the status
 * settings in the #NETLIST:
 * - If a new component is found in the #NETLIST and not in the #BOARD, it is added
 *   to the #BOARD.
 * - If a the component in the #NETLIST is already on the #BOARD, then one or more of the
 *   following actions can occur:
 *   + If the footprint name in the #NETLIST does not match the footprint name on the
 *     #BOARD, the footprint on the #BOARD is replaced with the footprint specified in
 *     the #NETLIST and the proper parameters are copied from the existing footprint.
 *   + If the reference designator in the #NETLIST does not match the reference designator
 *     on the #BOARD, the reference designator is updated from the #NETLIST.
 *   + If the value field in the #NETLIST does not match the value field on the #BOARD,
 *     the value field is updated from the #NETLIST.
 *   + If the time stamp in the #NETLIST does not match the time stamp  on the #BOARD,
 *     the time stamp is updated from the #NETLIST.
 * - After each footprint is added or update as described above, each footprint pad net
 *   name is compared and updated to the value defined in the #NETLIST.
 * - After all of the footprints have been added, updated, and net names and pin function
 *   properly set, any extra unlocked footprints are removed from the #BOARD.
