- Se cambiaron los 4 handlers de B4A a uno solo que toma el DB de la ruta automáticamente. - Se agregaron validaciones del numero de parametros y si el query no los requiere o se dan de mas o de menos, manda un error especificando eso, ya no se reciben errores directos de la base de datos, esto fue tanto para B4A como para JSON. - Se modificó el Readme.md para incluir todos estos cambios.
