function processOrgChartJS(fid,gp,gpmodel)
%PROCESSORGCHARTJS Writes Google org chart JavaScript for genes to an existing HTML file.
%
%   PROCESSORGCHARTJS(FID,GP,GPMODEL) writes the JavaScript for the
%   multigene regression model structure GPMODEL to the file handle FID
%   (which should be open for writing to and should be closed manually
%   after a call to this function).
