- If getImportances is set to true, the regressor will print a sorted
list of features and their importances, after performing training
- A REST action to retrieve the same list has been added

- When the start and end timestamps of a query are equal, it is enforced
that only one sensor value will be retrieved

- Staleness checks when performing sensor queries in the cache are
now enforced both in relative and absolute modes
- Fixed a race condition causing wrong results when performing queries
in absolute mode
- Changed logging in the TesterAnalyzer plugin

- Switched internal buffers to ureading_t types to allow the SensorBase
class to perform all basic overflow and wrap-around checks
- Managing overflows explicitly in the SAR parser, as deltas need to be
calculated beforehand

- Fixed install of BACNet headers on MAC OS
- Fixed install_conf target in analytics

- Test plugin that can be used to evaluate the performance and functionality
of the query engine and unit system

- use std::atomic_flag based spin lock for thread safety
- minor fixes and improvements

Pusher: Caliper plugin preparations: introduce sensor mutex to allow for runtime addition of sensors

- Also fixed a few compilation warnings

- An OpenCV-based regression plugin using Random Forest models
- Also added a few missing copy constructors

- A rather large library for machine learning, data analysis, filtering
and so on, that will likely cover ALL use cases we will ever have for the
data analytics framework

- Update/improve doxygen documentation
- Unify function name scheme of entity with SensorGroups
- Squash some TODOs

- Adapt Configurators:
  *Introduce partial template specialization in ConfiguratorTemplate
  *Move common logic to ConfiguratorInterface
  *Update and improve doxygen documentation
  *Adapt all plugin configurators
- Refactor printConfig of SensorGroups
- Minor improvements overall
