/**
* MongoURI handles parsing of URIs for mongodb, and falls back to old-style
* ConnectionString parsing. It's used primarily by the shell.
* It parses URIs with the following format:
*
* mongodb://[usr:pwd@]host1[:port1]...[,hostN[:portN]]][/[db][?options]]
*
* For a complete list of URI string options, see
* https://wiki.mongodb.com/display/DH/Connection+String+Format
*
* Examples:
*
* A replica set with three members (one running on default port 27017):
* string uri = mongodb://localhost,localhost:27018,localhost:27019
*
* Authenticated connection to db 'bedrock' with user 'barney' and pwd 'rubble':
* string url = mongodb://barney:rubble@localhost/bedrock
*
* Use parse() to parse the url, then validate and connect:
* string errmsg;
* ConnectionString cs = ConnectionString::parse( url, errmsg );
* if ( ! cs.isValid() ) throw "bad connection string: " + errmsg;
* DBClientBase * conn = cs.connect( errmsg );
