function runMAP1_14
% runMAP1_14 is a general purpose test routine that can be adjusted to
% explore different applications of MAP1_14
%
% It is also designed as 'starter' code for building new applications.
%
% A range of options are supplied in the early part of the program
%
% #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.
%
% #6
% Last minute changes to the model parameters can be made using
%  a cell array of strings, 'paramChanges'.
