• Corregir los errores mencionados arriba.
• Corregir todas las convenciones de nombres en los miembros del código original (métodos y parámetros mal nombrados) para facilitarle la tarea de búsqueda/identificación al compiler.
    También he corregido aquellas definiciones de nombres que podían resultar en ambiguaciones (ej: file),
    pues quiero recordarles que algunas palabras reservadas cómo "'type', 'from', es preferible "escaparlas" al definirlas como nombres de variables,
    y otros nombres como "file", al importar el espacio de nombres "System.IO.File", directamente es preferible evitar ese tipo de nombramientos ambiguos y utilizar algo más específico (ej: fileObj, fileName, filePath, etc).
• Añadir los Imports de los Namespaces requeridos para el uso del código, por los problemas que algunos usuarios han tenido con eso.
• Traslación de Módulo a Clase.
• Implementación de la interfáz IDisposable, para liberar la instancia de WhatsApp (WA) correctamente.
• Implementación de una excepción específica, 'WALoginFailedException', que sustituye a la terminación de ejecución en el método 'OnLoginFailed' del código original.
• Documentar todos los miembros del código. Aunque sigue siendo una documentación MUY incompleta a falta de documentación oficial por parte de los desarrolladores de la API para .Net.
