/**
 * ContainerNodeStruct: ordered heterogeneous collection of values.
 * - Notation: Custom name per instance
 *
 * A ContainerNodeStruct is identical to a Container type except that it represents tree data with a custom
 * BranchNodeStruct node. This special branch node represents the data of its entire sub tree as a value, instead
 * of a tree of nodes. This approach is a tradeoff:
 *
 * - More memory efficient
 * - Faster reads, since it doesn't require parsing merkleized data
 * - Slower hashing, since it has to merkleize the entire value everytime and has not intermediary hashing cache
 *
 * This tradeoff is good for data that is read often, written rarely, and consumes a lot of memory (i.e. Validator)
