BIG+RF+BK: remove the "cosmo_get_data_path" function, and replace it by the more general "cosmo_config" functionality. This avoids users changing code in the CoSMoMVPA repository
RF+BF: update the examples to use ">@@>" and "<@@<" for code to fill in, instead of ">>" and "<<"
NF: fx function, to apply a function to unique combinations of .sa or .fa values
RF+BK: use pre-computed odd and even nifti files with t values
