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
