- make use of new EntityInterface
- _keepRunning is now a bool
- extend and improve (doxygen) documentation

- Removed the dlclose call on plugin unloads to avoid segmentation fault
issues at destruction time of boost thread objects due to failed symbol resolution
- QueryEngine in DCDBPusher does not block anymore while being updated,
but simply returns NULL

- In the new implementation the sensor map used to speed up access to
sensor data is rebuilt synchronously when plugins are reloaded/loaded/unloaded
- Any threads accessing the sensor query callback will block until
the update has finished

- The MQTT topic of a sensor is now used to identify the file name of the
sink and is appended to the path given as input

- New method is lock-based and compatible with all features (e.g. REST API)
in the framework
- Performance impact is expected to be negligible as race conditions will
not be frequent

- Template for Job Analyzers, derived from AnalyzerInterface

- "Fixed" segmentation fault occurring after the return of dcdbpusher's
main by not unloading dynamic libraries in PluginManager's destructor
- Error log messages in Aggregator plugin changed to Debug level
- Added Wno-unused-variable and Wno-unused-function compile flags
- Tweaked the stop method of TesterSensorGroup
- Re-worked the destructor of SARParser in ProcFS plugin

Move CXXFLAGS definitions to config.mk and thus streamline compiler flags for all Makefiles in subdirectories

- This feature is not needed anymore in the new REST API design, and
forward slashes are parsed correctly without additional logic

- Analytics plugins can be now loaded and unloaded dynamically
- DCDBPusher now looks into the current configuration directory if no
path is supplied when loading/reloading a plugin

- Changes mostly affect the REST API

- Added documentation to the new SensorID implementation
- NOTE: virtual sensors will likely require some modifications due to
how topics are handled now ('/' separator clashing with divide symbol)

dcdbpusher: New PluginManager class to bundle all plugin related operations. Integration outstanding

- String topics are now used across all of DCDB, up to Cassandra
- As of now, sensor names ALWAYS match MQTT topics
- Users can still define sensor "aliases" via dcdbconfig that point
to the same topics

- Update config files to reflect new topic structure
- Updated READMEs accordingly
- Added support for "relaxed" analyzers, whose units can be built
even if some sensors cannot be found in the system
- Added support for sub-units, so as to build hierarchical unit structures
