+/// <summary>
+/// This example sets up the Hierarchical Keyring, 
+/// which establishes a key hierarchy
+/// where "branch" keys are persisted in DynamoDb.
+/// These branch keys are used to protect your data keys,
+/// and these branch keys are themselves protected by a KMS Key.
+/// 
+/// Establishing a key hierarchy like this has two benefits:
+/// 
+/// First, by caching the branch key material, and only calling
+/// KMS to re-establish authentication regularly according to your configured TTL,
+/// you limit how often you need to call KMS to protect your data.
+/// This is a performance/security tradeoff, where your authentication, audit, and
+/// logging from KMS is no longer one-to-one with every encrypt or decrypt call.
+/// Additionally KMS Cloudtrail cannot be used to distinguish Encrypt and Decrypt calls,
+/// and you cannot restrict who has Encryption rights from who has Decryption rights
+/// since they both ONLY need KMS:Decrypt.
+/// However, the benefit is that you no longer have to make a
+/// network call to KMS for every encrypt or decrypt.
+/// 
+/// Second, this key hierarchy facilitates cryptographic isolation
+/// of a tenant's data in a multi-tenant data store.
+/// Each tenant can have a unique Branch Key,
+/// that is only used to protect the tenant's data.
+/// You can either statically configure a single branch key
+/// to ensure you are restricting access to a single tenant,
+/// or you can implement an interface that selects 
+/// the Branch Key based on the Encryption Context.
+/// 
+/// This example demonstrates configuring a Hierarchical Keyring
+/// with a Branch Key ID Supplier to encrypt and decrypt data for
+/// two separate tenants.
+/// 
+/// This example requires access to the DDB Table where you are storing the Branch Keys.
+/// This table must be configured with the following
+/// primary key configuration:
+/// - Partition key is named "partition_key" with type (S)
+/// - Sort key is named "sort_key" with type (S)
+/// 
+/// This example also requires using a KMS Key.
+/// You need the following access on this key:
+/// - GenerateDataKeyWithoutPlaintext
+/// - Decrypt
