Also starting a runtime record class, currently in __init__.py

uw_record gives information on the installation and runtime

Access via:
import underworld3 as uw
uw.uw_record.get_installation_data
uw.uw_record.get_runtime_data

* uw_record lives in underworld/utilities/__init__.py
* uw_record collects data only on proc 0 and broadcasts to all procs.
  For get_runtime_data be aware of this design. As calling often could cause
  an operational overhead. While get_installation_data only bcasts at initialisation.
* Coming idea is to serialised the output get_installation_data into
  hdf5 files

* access via underworld3.auditor
* test included in test_0005_utils.py
