* Proper shutdown for ssl and non-ssl connections
* Report session id in history
* Report histogram of requests per session
* Change print name to 'http'
* Split logging into "HTTP" and "HTTP-RPC" partitions
* More logging and refinement of logging severities
* Log the request count when a session is destroyed
* Remove obsolete config variables
* Reduce coupling
* Use C++11 ownership containers
* Use auto when it makes sense
* Detect edge-case in unit tests
* Reduce the number of LedgerEntrySet public members
* reduce duplicated code using templates
* replace BOOST_FOREACH with C++11 for loops
* remove most direct calls to new
* limit line length to 80 characters
* clearly identify virtual and overridden methods
* split STObject and STArray into their own files
* name files after the class they contain
* Split adjustOwnerCount to increment and decrement paths.
* Move pathfinding-specific functions out of LedgerEntrySet
* Convert members to free functions
* New CreateTicket transactor to create tickets
* New CancelTicket transactor to cancel tickets
* Ledger entries for tickets & associated functions
* First draft of M-of-N documentation
* streambuf wrapper supports rvalue move
* message class holds a complete HTTP message
* body class holds the HTTP content body
* headers class holds RFC-compliant HTTP headers
* basic_parser provides class interface to joyent's http-parser
* parser class parses into a message object
* Remove unused http get client free function
* unit test for parsing malformed messages
* Change public members of Input and Output to remove trailing _.
* Remove Input constructor and separate flags in RippleCalc to reduce
duplication and confusion.
* Make calculation result private; add getter.
* Narrow scope of some of the results of calls to rippleCalculate.
To improve compatibility with the proposed std::optional a number
of changes were made, one of which is the removal of the implicit
conversion to bool. As a result, returning boost::optional as a
bool value now fails. Explicit conversion to bool used for clarity.
* Properly handle both unsigned and signed integers
* Return parsing error for overlong JSON numbers
* Implement unit test checking the edge cases that are of interest
