Added test function for two conversion functions.

  + artoa.convert.rawToa2PhaseRefTime
  + artoa.data.addFloatOffsetAndSignalLength

+tests/+data/toaConversion.m

+function [success] = toaConversion()
+%TOACONVERSION Tests if the TOA conversion is correct.
+% Uses the variable TOA of float_0272.mat file to check if the calculations
+% are correct.
+
+[currentDirectory, ~, ~] = fileparts(mfilename('fullpath'));
+dataFileName = fullfile(currentDirectory, '..', 'data', '0272.rfb');
+float = artoa.load.rfb(dataFileName);
+
+% load test mat file exported from old version of artoa3
+load(fullfile(currentDirectory, '..', 'data', 'float_0272_globals.mat'));
+
+global TOA;
+
+convertedToPhaseRefTime = artoa.convert.rawToa2PhaseRefTime(float);
+
+convertedToa = artoa.data.addFloatOffsetAndSignalLength(float, convertedToPhaseRefTime);
+
+success = ~any((TOA - convertedToa) > 0);
