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
%                 [numlow nummid numhigh]
%
%   Output parameters:
%     sponts    : nerve fibres
%     tabs      : absolute timing info
%     trels     : relative timing info
%
%   BRUCE2018_GENERATEANPOPULATION generates an AN population for a 
%   given absolute number of nerve fibres and relative proportion of
%   low- mid- and highly-spontaneously firing nerve fibres
