/**

 * @author fjp

 *

 * El prop?sito de esta clase es centralizar el manejo de la

 * edici?n. Aqu? podemos encontrar una lista con todas

 * los temas en edici?n, y las propiedades que sean globales

 * e interesantes a la hora de ponerse a editar.

 * Por ejemplo, podemos poner aqu? el Grid que vamos a usar,

 * el MapControl que tenemos asociado, etc, etc.

 * Tambi?n ser? el responsable de mantener una lista de

 * listeners interesados en los eventos de edici?n, y

 * de lanzar los eventos que necesitemos.

 * Lo principal es una colecci?n de LayerEdited, y cada

 * LayerEdited es un wrapper alrededor de un tema que guarda

 * las propiedades de la edici?n.

 *

 * Nuevo: Llevar aqu? el control de las tablas en edici?n tambi?n

 * y centralizar los listeners interesados en los eventos de edici?n.

 *

 * TODO: Poner todo lo referente al EditionManager dentro de una vista.

 * para permitir tener varias vistas con temas en edici?n

 *
