// SEAICE_CONFIG
// This file is used to store configuration information for the Sea Ice Index.
// This will allow these to be more easily modified, as well as removing them
// from the code itself.


// captionText
// This array stores the various possible captions.  The code will look for 
// the mathing timeType to display the caption.  This timeType will be found
// in the individual image information below.
// To add a new timeType, if necessary:
//   1) Add a comma (,) immediately after the closing brace (}) of the last 
//      entry in the list.
//   2) Add a new caption object, which will be in the following format:
//          {                           <-- opening brace for object
//              id      : '[TYPE]',     <-- replace [TYPE] with the identifier for the caption
//              header  : '[HEAD]',     <-- replace [HEAD] with the header text of the caption
//              caption : '[CAPTION]'   <-- replace [CAPTION] with the caption text
//          }                           <-- closing brace for object
//      The [BRACKET] values should be replaced as described.  Don't forget
//      to include the single quote (') and comma (,) characters shown above!
