- Move everything back to GaudiExamples
- Split declaration and definition of templates
- Clarify stuff that needs changing in registerCondition
- Simplify state management

There is some interface surface in ConditionContext and
ConditionAccessorHolder which we only want to expose to
ConditionAccessors that are configured with the right ConditionContext.
This is handled by friending the ConditionAccessor.

We cannot do this in a design where the ConditionAccessor is templated
on the ConditionContext, because then we must friend only the
ConditionAccessor instances that matches _our_ ConditionContext, and
that in turn cannot be done because in C++, friend templates cannot be
partial specialization.

The forward compatible syntax from 2.6 plus is:

    except SomeException as err

rather than

    except SomeException, err
