Detailed Description
Predicate for generating connections which a connection probability which depends on the lateral distance between SimObjects.The connection probability is C * exp( -|pi-pj|^2 /2/ lambda^2 ) where |pi-pj| is the Euclidian distance between the SimObject's locations pi and pj in the x-y plane. Self connections are not made.

Return true if a uniform distributed random number is smaller than C * exp( -|px-py|^2 /2/ lambda^2 ).
Self connections are not made by returning false if ID(src) == ID(dst).
