%            opcional * [ENCABEZADO ALTERNATIVO]{ENCABEZADO}
%    Comando genérico para el inicio de sección.
%    NOMBRE          : ejemplo, 'subsección'
%    NIVEL           : un número, denotando profundidad de la sección -- ejemplo: capítulo=1,
%                      sección=2, etc.
%    IDENTACIÓN      : Indentación del encabezado desde el margen izquierdo
%    ANTES DE SALTO  : Valor absoluto = salto a nivel superior del encabezado.
%                      Si es negativo, entonces se suprime la identación del texto que sigue al encabezado.
%    DESPUÉS DE SALTO: si es positivo, entonces es el salto a dar después del encabezado, de lo contrario, 
%                      es el salto a dar a la derecha del encabezado actual. 
%    ESTILO          : comandos para la configuración de estilo
%  Si falta el '*', entonces se incrementa el contador. Si está presente, entonces no debería haber un argumento en encabezado alternativo
%  Utilice el contador 'secnumdepth' cuyo valor es el mayor nivel de la sección a ser enumerada
