- Now using references instead of pointers
- Return type is now bool

- Make clean might be required

- The "observations" operation simply counts the number of total queried
elements over the inputs of each unit

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

- Compiles fine but completely untested for the moment
- Also addressed many bugs for job analyzer templates

- Now supports also standard deviation and percentile computation
- Multiple output sensors per analyzer can be defined, each performing
a different aggregation task
- QueryEngine has been slightly modified so as not to clear the input
sensor reading buffer (if any), thus allowing to accumulate sensor
values with subsequent calls

- "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

- QueryEngine integration done (but not functional yet, debugging required)
- Changed behavior on exceptional conditions: if SensorNavigator or
AnalyticsManager initialization fails, termination follows
- Now the QueryEngine can also access output sensors of other Analyzers
- Minor bugfixes

- First step for integration of the analytics framework in the collectagent
- QueryEngine and REST API integration still missing
- Proper testing still to be done
- Added a probe function: the global config file is scanned before
initialization, and if no data analytics plugins are requested, no
sensor navigator is built

- A nicer and refactored version of the "average" plugin
- Allows to perform arbitrary aggregation operations over sensors, like
sum, average, or maximum
