A proxy module is a module with a known structure, but
accessed over a SECoP connection.
For the configuration, a Frappy module class has to be given.
The proxy class is created from this, but does not inherit from it.
However, the class of the returned object will be subclass of the
SECoP base classes (Readable, Drivable etc.).
A possible extension might be, that instead of the Frappy class,
the JSON module description can be given, as a separate file
or directly in the config file.
Or we might offer a tool to convert the JSON description to
a python class.

new client intended as base class for all clients
- based on Ennos secop client in nicos ([WIP] provide secop client)
- self healing connection singletons
- extension for other than TCP is foreseen (by extending new uri schemes)
- extensible name mangling
- seperate rx and tx threads supporting events
- internal cache
- extensible error handling
- callback for unhandled messages
- callback for descriptive data change
- callback for node stat change (connected, disconnected)
- a short close down and reconnect without change in descriptive data
does not disturb the client side
works with secop-gui (change follows), planned to be used for Frappy
internal secop proxy and as a replacement for secop.client.baseclient.Client
in the nicos secop device.
-> secop/client/baseclient.py to be removed after planned changes
moved secop/client/__init__.py to secop/client/console.py because secop.client
would be the natural place to put the new base class.

will autogenerate its communicator.
The iodevClass attribute on the module class determines the class
for the iodev to be generated.

in the current implementation, in case polling results in an error,
an error_update is generated. But on activate, for this parameter
a normal update will be generated, indicating that this value is ok.
With this change, parameters have an additonal attribue 'readerror',
which save the error generated on the last read, or None, if the
read was successful.
In addition, subsequent repeated errors are only reported the first
time.

polled.

with Status enum type)

this change is triggered by the fact, that assigining a unit
in the config file did no longer work.
this change has several implications:
1) secop.properties must not import secop.datatypes:
- as ValueType can not be imported, the default behaviour with
'mandatory' and 'default' arguments was slightly changed
- instead of checking for DataType when exporting, a try/except
was used
2) the datatype of datatype properties is sometimes not yet defined.
a stub is used in this cases instead, which is later replaced by
the proper datatype. The number of stubs may be reduced, but this
should be done in a later change, as the diff will be much less
readable.
3) in config files, datatype properties can be changed like parameter
properties. HasProperties.setProperties/checkProperties/getProperties
are overridden for this.
the config editor seems still to work, an issue (probably py3) had
to be fixed there
