Detailed Description

Helper for writing unit tests with controlled ledger histories.

This class allows clients to refer to distinct ledgers as strings, where each character in the string indicates a unique ledger. It enforces the uniqueness at runtime, but this simplifies creation of alternate ledger histories, e.g.

HistoryHelper hh; hh["a"] hh["ab"] hh["ac"] hh["abd"]

Creates a history like b - d / a - c

Ledger const & ripple::test::csf::LedgerHistoryHelper::operator[] ( std::string const & s )

Creates any necessary intermediate ledgers, but asserts if a letter is re-used (e.g. "abc" then "adc" would assert)
