dpinelo: Este método es una extensión de nextCounter pero permitiendo la introducción de una primera
secuencia de caracteres. Es útil cuando queremos mantener diversos contadores dentro de una misma tabla.
Ejemplo, Tabla Grupo de clientes: Agregamos un campo prefijo, que será una letra: A, B, C, D.
Queremos que la numeración de los clientes sea del tipo A00001, o B000023. Con esta función, podremos
seguir usando los métodos counter cuando agregamos esa letra.
Este metodo devuelve el siguiente valor de un campo tipo contador de una tabla para una serie determinada.
Este metodo es muy util cuando se insertan registros en los que
la referencia es secuencial según una secuencia y no nos acordamos de cual fue el último
numero usado. El valor devuelto es un QVariant del tipo de campo es

del campo sea 'String' porque así se le puede dar formato y ser
usado para generar un código de barras. De todas formas la función

@param serie serie que diferencia los contadores
