The "ledger header" is the chunk of data that hashes to the
ledger's hash. It contains the sequence number, parent hash,
hash of the previous ledger, hash of the root node of the
state tree, and so on.
The term "ledger base" refers to a particular type of query
and response used in the ledger fetch process that includes
the ledger header but may also contain other information
such as the root node of the state tree.
