Improved error messages for bigData custom track common mistakes likemissing bigDataUrl setting or trying to upload a bigData file instead
of making a track line with a public URL.  I added a new "factory"
to customFactory.c that produces no tracks, only error messages about
directly uploaded bigData files.
