    Allows defining of custom SQL types

    Args:
        type: the web2py type (default = 'string')
        native: the backend type
        encoder: how to encode the value to store it in the backend
        decoder: how to decode the value retrieved from the backend
        validator: what validators to use ( default = None, will use the
            default validator for type)

    Example::
        Define as:

            decimal = SQLCustomType(
                type ='double',
                native ='integer',
                encoder =(lambda x: int(float(x) * 100)),
                decoder = (lambda x: Decimal("0.00") + Decimal(str(float(x)/100)) )
                )

            db.define_table(
                'example',
                Field('value', type=decimal)
                )
