   * priority range shall be between 0 and 9. Neither less than 0 nor greater than 9 shall it be, but 0-9 shall be the range of the priority.
   
   * there are two ways that a user can make a message get a priority.   One is by assigning the message a priority directly. The other is by sending the message to an address that has a priority assigned to it.    In the Dispatch Router config file, when you are defining an address, you can stick a priority descriptor in there.  And if a message with a priority gets sent to an address with a priority, then the address priority wins.
   
   * priority only affects how messages are processed on inter-router links between interior routers.
   
   * Higher numbers are higher priority. It's not like golf.
   
   * The reason the default  priority is 4 is so that you can set some message to be *lower* than default if you want to.
   
   * If you set a message's priority to 0 we just don't bother sending it at all. Who cares? Instead we break it down into its constituent 1s and 0s which are then used as lubricant in the code.
   
   * That last point ^^^ is completely false. Sorry.  Low blood sugar.
