/**

* <p>
|
||
|
|
* Element List is a list of elements and ranges. The ranges refer to the {@link TextPanel} locations
|
||
|
|
* where the text for that element is found. The {@link #getElement} method takes an integer location
|
||
|
|
* in the TextPanel and returns the <code>org.jdom.Element</code> that is associated with that location
|
||
|
|
* <i>if ther is one</i>! If not, it returns <code>null</code>, indicating there is nothing to edit at
|
||
|
|
* that location. This is created by the TextPanel and given to the {@link TiblEdit} controller so
|
||
|
|
* it can turn on and off menu options and functionality, depending on the position of the cursor in
|
||
|
|
* the TextPane.
