/*

  ## Stringquery

  Broadcasts a query object to other panels

  ### Parameters
  * label ::  The label to stick over the field 
  * query ::  A string or an array of querys. String if multi is off, array if it is on
              This should be fixed, it should always be an array even if its only 
              one element
  * multi :: Allow input of multiple queries? true/false
  * multi_arrange :: How to arrange multu query string panels, 'vertical' or 'horizontal'
  ### Group Events
  #### Sends
  * query :: Always broadcast as an array, even in multi: false
  #### Receives
  * query :: An array of queries. This is probably needs to be fixed.
