Added plot function for the trajectory reference position.

lib/+artoa/+trajectory/plotTrajectoryReferencePositions.m

+function [scatterHandles, textHandles] = plotTrajectoryReferencePositions(pAxesHandle, pTrajectory)
+%PLOTTRAJECTORYREFERENCEPOSITIONS Summary of this function goes here
+%   Detailed explanation goes here

+%% Prepare variables
+referencePositions = pTrajectory.trackParameter.soundsourceCombinations.referencePosition;
+referencePositions = cellfun(@strsplit, referencePositions, 'UniformOutput', false);
+referencePositions = cellfun(@str2double, referencePositions, 'UniformOutput', false);
+referencePositions = cell2mat(referencePositions);

+x = referencePositions(:, 2);
+y = referencePositions(:, 1);
