Now rpc-method ID is passed to traceback() function of the BaseRPCParser class
Fixed typo in comment
Added support for logging requests, responses and errors. Example:

from tornadorpc.base import config
from tornadorpc import start_server

"""
logger() is function with params:
     action - one of the following strings: 'request', 'response' or 'error'
     body   - json text of the request or response. Or stacktrace if error
"""
def logger(action, body=None):
    colon = ""
    if body:
        colon = ":"
    print "%s   %s%s" % (datetime.now().strftime('%d.%m.%Y %H:%M:%S'), action.capitalize(), colon)
    if body:
        print body

config.logger = logger
start_server(...)
Merging changes, providing requests logging
