/**
* Represents a constant value of type GUID which can be compared against the base64 representation of the GUID
* that is stored in the underlying table storage.
*
* This is used to hold GUID values that are provided in the query (using the `guid'...'` syntax), for example
* the query `PartitionKey eq guid'00112233-4455-6677-8899-aabbccddeeff'` would contain a `GuidNode` with the value
* `00112233-4455-6677-8899-aabbccddeeff`.
*
* NOTE: This node type also exposes a `legacyStorageFormat()` method which returns the GUID in its string representation
* for backwards compatibility with the legacy table storage format.
