Done.

They cannot be raised by the functions in this module. However they can be raised when some of the simple_store methods are called directly, like i do in my pul module. 
An example could be a PUL which requires to insert a node with an identity which is already assigned to another node. (Either the same PUL/operation is applied twice or the user is using crafting ids). In those function these errors are either catched and wrapped into other errors or thrown.
