  //  fonts, weights and styles in one include. This does not affect 
  //  the output compared with individual includes (recommended). 
  //
  //  You can en-/disable each feature individually.
  //  Be aware of output as all combinations will be added to the import. 
  //  Also note that when multi-fonts is enabled all multi word font names
  //  like Open Sans must be quoted 'Open Sans'
  // 
  //  By default only multiple weights are allowed as it is what  
  //  is most likely to be used and does not cause unforseen
