[Zope3-checkins] SVN: Zope3/trunk/src/RestrictedPython/SafeMapping.py Deleted an unused module.

[Shane Hathaway]

Log message for revision 28490:
  Deleted an unused module.
  
  No Zope 3 code uses SafeMapping, and SafeMapping depends on a Python 
  extension module (MultiMapping) not present in Zope 3.  In fact, if you 
  import SafeMapping using the API documentation browser, and you happen
  to have ZODB 3.2 installed, Python crashes with a fatal error related in 
  some way to ExtensionClass.
  
  

Changed:
  D   Zope3/trunk/src/RestrictedPython/SafeMapping.py
