%plotPointTracking

%INPUT: Tracking, Params, frame, frame index
%OUTPUT: Behavior.Freezing structure

%FUNCTION: calculate the freezing frames via transformation of data from
%the Metrics structure and save into Behavior structure

% Future: Calculate average velocity of body; test in place of
% RearBackVelocity
