pEchoVar
===============================================
o Added Boolean Switching. For a configuration "Echo = FOO !-> BAR", if a string 
  representing a Boolean value is published to FOO, a string representing the 
  opposite Boolean value is published to BAR. The case of the strings is matched.


BHV_AvoidColregsV17
===============================================
o Turned off debugging output inadvertantly left enabled.


uFldCollisionDetect Documentation
===============================================
o substantial additions and corrections

 
pMarineViewer
===============================================

o Added functionality to the Commander pop-up window including
  auto-adjusting button widths, and the ability to add color to a
  button to make it easier for an operator to find and hit an
  emergency button.

o Updated the pMarineViewer documentation to describe commander
  pop-up window functionality. The commander pop-up window feature
  was part of the 17.7 release but was not documented at all.

o The m2_berta mission has been updated to include a non-trivial
  example of the commander pop-up window, to control deploying,
  returning, station-keeping, vehicle speed, and loiter direction
  for both vehicles.

pHelmIvP
===============================================
o Lazy behavior evaluation (TBD)


pBasicContactManager
===============================================
o Added the ability to have alerts based on a polygon regions, so
  missions can be configured to trigger action if a contact of 
  interest enters a given region. Region criteria can be used 
  in conjunction with range criteria, or simply on its own.
o ToDo: ignore contacts from different teams
        buffer value to avoid thrashing
