Currently, the random attribute node doesn't work well for most workflows because for any change in the input data it outputs completely different results. This patch adds an implicit seed attribute input to the node, referred to by "id". The attribute is hashed for each element using the CPPType system's hash method, meaning the attribute can have any data type. Supporting any data type is also important so any attribute can be copied into the "id" attribute and used as a seed. The "id" attribute is an example of a "reserved name" attribute, meaning attributes with this name can be used implicitly by nodes like the random attribute node. Although it makes it a bit more difficult to dig deeper, using the name implicitly rather than exposing it as an input should make the system more accessible and predictable.
