 /**
  * A component used to collect a provided date from the user using a client-side JavaScript calendar. Non-JavaScript
  * clients can simply type into a text field.

  * One aspect here is that, because client-side JavaScript formatting and parsing is so limited, we (currently)
  * use Ajax to send the user's input to the server for parsing (before raising the popup) and formatting (after closing
  * the popup). Weird and inefficient, but easier than writing client-side JavaScript for that purpose.
