function testBM (BMlocations, paramsName,...
    relativeFrequencies, AN_spikesOrProbability, paramChanges)
% testBM generates input output functions for DRNL model for any number
% of locations.
% Computations are bast on a single channel model (channelBFs=BF)
% peak displacement (peakAmp) is measured.
%  if DRNLParams.useMOC is chosen, the full model is run (slow)
%  otherwise only DRNL is computed.
% Tuning curves are generated based on a range of frequencies reletove to
% the BF of the location.
