docs: Parses the parameters of the given request query part and creates a parameter map out of them.<p>
  
  Please note: This does not parse a full request URI/URL, only the query part that
  starts after the "?". For example, in the URI <code>/system/index.html?a=b&amp;c=d</code>,
  the query part is <code>a=b&amp;c=d</code>.<p>
  
  If the given String is empty, an empty map is returned.<p>
  
  @param query the query to parse
  @return the parameter map created from the query
