> When using the Materialized object if the user wants to name the statestore 
> with
> {code:java}
> Materialized.as("MyStoreName"){code}
> then subsequently provide the key and value serde the calls to do so must 
> take the form of 
> {code:java}
> Materialized.as("MyStoreName").withKeySerde(keySerde).withValueSerde(valueSerde)
> {code}
> If users do the following 
> {code:java}
> Materialized.as("MyStoreName").with(keySerde, valueSerde)
> {code}
> the Materialized instance created by the "as(storeName)" call is replaced by 
> a new Materialized instance resulting from the "with(...)" call and any 
> configuration on the first Materialized instance is lost.
