There is an inconsistency in the __str__ function of the MetaData class and the naming of the actual field of the class.

Example:

In [1]: import rsb

In [2]: a=rsb.Event()

In [3]: print a
Event[id = None, scope = 'Scope[/]', data = 'None', type = '<type 'object'>', 
method = 'None', metaData = MetaData[create = 1468851183.69, send = None, 
receive = None, deliver = None, userTimes = {}, userInfos = {}], causes = []]

In [4]: a.metaData.create
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-4-a56d9880b1f7> in <module>()
----> 1 a.metaData.create

AttributeError: 'MetaData' object has no attribute 'create'

In [5]: a.metaData.send
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-5-3f713903c3a3> in <module>()
----> 1 a.metaData.send

AttributeError: 'MetaData' object has no attribute 'send'

In [6]: a.metaData.createTime
Out[6]: 1468851183.694944

This behaviour is unexpected and might confuse users. The easy fix is to use the actual field name in the __str__ function. Patch attached.
