docs: Generate a location selector for each configured
  subview type. Each subview type will have a
  location set based on the subview type. For
  example,the subview type 'header' would get the
  type '.header-container' (using the default
  suffix).
  @memberOf SubViewManager#
  @param  {string} [suffix=-container]
  The suffix to use for each location
  selector.
  @return {SubViewManager}
