MeasurementGroup
Class that manages a serializable object containing a set of features.
It gathers a list of measurements in a same object that can be set into an AnalysisMsr object. The main benefit of using a MeasurementGroup object is its serialization mechanism to save it and recall it later.

| MeasurementGroup() | Default constructor. |
| MeasurementGroup( std::vector< MsrInfo> msrInfos ) | Constructor from a predefined list of measurements. |
| void add( MsrInfo msrInfo ) | Adds a measurement into the MeasurementGroup object. |
| void add( const std::vector< MsrInfo> msrInfos ) | Adds a list of measurements into the MeasurementGroup object. |
| void remove( MsrInfo msrInfo ) | Removes a measurement from the MeasurementGroup object. |
| void remove( const std::vector< MsrInfo>f msrInfos ) | Removes a list of measurements from the MeasurementGroup object. |
| std::vector< MsrInfo> getMeasurements() | Returns the list of measurements embedded in the MeasurementGroup object. |
| void read( const String& pathFile ) | Reads the MeasurementGroup object from a file path. |
| void write( const String& pathFile, bool overWrite = true ) | Writes the MeasurementGroup object into a file defined by a path. |
