function [sponts,tabss,trels]=bruce2018_generateanpopulation(numcfs,numsponts)
%bruce2018_generateanpopulation generates an AN population for a given number of nerve fibres and numsponts
%
%   Usage:
%     [sponts,tabss,trels]=bruce2018_generateanpopulation(numcfs,numsponts)
%
%   Input parameters:
%     numfcs    : number of frequencies
%     numsponts : number of low- mid- and highly-spontaneously firing nerve fibres

%
%   Output parameters:
%     sponts    : nerve fibres
%     tabs      : absolute timing info
%     trels     : relative timing info
