.pointDistance          Alternative point distance (and direction)
                        calculations

                        package
adj                     Fast 'adjacent' function, and Just In Time
                        compiled version
agentLocation           'SELES' - Agent Location at initiation
cir                     Identify pixels in a circle or ring (doughnut)
                        around an object.
cirSpecialQuick         This is a very fast version of 'cir' with
                        'allowOverlap = TRUE', 'allowDuplicates =
                        FALSE', 'returnIndices = TRUE',
                        'returnDistances = TRUE', and 'includeBehavior
                        = "excludePixels"'. It is used inside
                        'spread2', when asymmetry is active. The basic
                        algorithm is to run 'cir' just once, then add
                        to the x,y coordinates of every locus.
