---------------------------+------------------------------------------------
 The current Expression Editor at the moment is nothing more than a
 simplistic text field for any editor that requires it. There are few
 things that can improve the usability of this component:

 * Switching the font to plain text. Makes lining up all those parentheses
 much easier
 * Utilising the response of GetCapabilities. It contains the list of
 expression functions supported by that provider (which we can easily get),
 along with return and argument information. By presenting the user with
 the list of supported expressions, this also prevents the user from
 entering unsupported expressions. It's like pseudo-intellisense.

 Essentially it would be best to make it look and function something
 similar to the Expression Editor in FDO Toolbox.
