Logger

Update the logger to allow multiple lines to be processed for each ostringstream. This will allow for a simpler and more efficient debugging method. No need to all Logger::Log(LoggerLevel) several times.

Simplify the Logger API so it is easier to use. Maybe use a macro or something to call the functions.

define LOG Logger::Log("What we want to log", DEBUG);
