v1.7.11

-- Added another data set to set of unit tests Example4_twNI. 
-- Added logging to unit tests so that the test results are saved in a .log file
-- Cleaned out Example9_SessRuns/Simple_Probe4_* of procResults data with Homer2_UI's resetGroupFolder to minimize .nirs file size. 
-- Added FindUnitTestsFolders to automatically find all group data folders that can be tested. Which means you must only generate the homer2 groupResults_homer2_lpf_*.mat files and place the data folder in the UnitTests folder and the unit tests will recognize that it is a testable folder and automatically apply the same tests as to the other folder.
-- Added UnitTestAll, the mother of all unit tests.
