function test_IC_DominikaTones
% test_MAP1_14 is a general purpose test routine that can be adjusted to
% test a number of different applications of MAP1_14
%
% A range of options are supplied in the early part of the program
%
% One use of the function is to create demonstrations; filenames <demoxx>
%  to illustrate particular features
%
% #1
% Identify the file (in 'MAPparamsName') containing the model parameters
%
% #2
% Identify the kind of model required (in 'AN_spikesOrProbability').
%  A full brainstem model (spikes) can be computed or a shorter model
%  (probability) that computes only so far as the auditory nerve
%
% #3
% Choose between a tone signal or file input (in 'signalType')
%
% #4
% Set the signal rms level (in leveldBSPL)
%
% #5
% Identify the channels in terms of their best frequencies in the vector
%  BFlist.
%
% Last minute changes to the parameters fetched earlier can be made using
%  the cell array of strings 'paramChanges'.
%  Each string must have the same format as the corresponding line in the
%  file identified in 'MAPparamsName'
%
% When the demonstration is satisfactory, freeze it by renaming it <demoxx>
