Fixes #28

Started implementing consistent macro pulse numbers in process variables. Only scalars at the moment.
No dediacted tests yet, but adapted ZMQ test which failed.

It breaks on bionc (don't know why)

This reverts commit cdd0598b.

This commit belongs to issue #4, allow to set the EqFct code in mapping file.
In VariableMapper a std::map with location(string) and code(int) was added.
With getLocationAndCode() this map is returned and used in eq_creat.cc to add missing locations with
10 default, or with 'code' set in the <location> tag in the mappinmg xml file.

To be reverted once DOOCS with an eq_exit method has been released

Otherwise we run into a deadlock or random crashes

Follow-up fix for 32d3728c

It seems that setting up zmq might take longer than expected. Add
additional delay and move initial write after subscription to make sure
we really receive the inital event

The change in test application causes FROM_DEVICE values to be written
only if the TO_DEVICE variables are modified.

It basically decorated the AutoPropertyDescription with the type which
is now in AutpPropertyDescription

Helps debugging a bit

Bubble up the type to the parent class

change type of macro pulse number PV to int64_t (as this is the data type expected by DOOCS) and convert if necessary via the TypeChangingDecorator
