"""
Generic error hierarchy
Leap/EIP exceptions used for exception handling,
logging, and notifying user of errors
during leap operation.
Exception hierarchy
-------------------
All EIP Errors must inherit from EIPClientError (note: move that to
a more generic LEAPClientBaseError).
Exception attributes and their meaning/uses
-------------------------------------------
* critical: if True, will abort execution prematurely,
after attempting any cleaning
action.
* failfirst: breaks any error_check loop that is examining
the error queue.
* message: the message that will be used in the __repr__ of the exception.
* usermessage: the message that will be passed to user in ErrorDialogs
in Qt-land.
TODO:
* EIPClientError:
Should inherit from LeapException
* gettext / i18n for user messages.
