; @brief	Crea la estructura de las paginas segun el modelo de memoria deseado
; @details	Lo hace para un modelo de paginacion PAE de 4KB de tamaño de pagina.
; 		Posee 3 tablas de paginas, 1 tabla de directorio de pagina y 1 tabla 
; 		de punteros de directorios de paginas. Cada una de las tablas de paginas
;		posee capacidad de mapear 0x200 bloques de 4KB cada. Lo atributos
;		de las tablas de paginas y directorios de paginas son Supervisor, R&W
;		y presentes, mientras que las entradas de la PDTP es simplemente presente.
