Add BatchAttribute

[Beffyman]

Add the following Attribute to the generator to influence generation.

BatchAttribute(int count)

Said attribute will require the following structure to be usable: IEnumerable<T> return type At least one IEnumerable<K> parameter. Other parameters are allowed and will be reused on each request.

Multiple requests will be paged from the IEnumerable<K> parameter with other parameters and be aggregated into the result of IEnumerable<T>

Use of this attribute will be rare, but only for large request loads that would either time out or reach max uri lengths unless done.
