It is certainly not a constructor race. Normally items are initialized
within a class according to the order of their appearance.

// We use m_Parent->GetDesignSettings() to get some default values
// But when this function is called when instantiating a BOARD class,
// by the NETCLASSES constructor that calls NETCLASS constructor,
// the BOARD constructor (see BOARD::BOARD) is not yet run,
// and BOARD::m_designSettings contains not yet initialized values.
// So inside the BOARD constructor itself, you SHOULD recall SetParams
