Subject: Agrego ToRaw a las claves.
X-Git-Tag: 1_0-pre2~28
X-Git-Url: https://git.llucax.com/z.facultad/75.52/treemulator.git/commitdiff_plain/57dbb7df8973a3e0c0c570c1eae9d84802e02bd9?ds=inline;hp=58f5f2e6ba6f33bc457e98ec883f2834c9a5fe6f

Agrego ToRaw a las claves.
Este nuevo metodo es parecido a ToArray, solo que muestra la clave
tal cual se leyo del disco. Es necesario para mostrar luego las claves
abreviadas y esas cosas.
