A generic interface for a wide-variety of sensors designed to be used in the application RawLogGrabber.
Derived classes should be designed with the following execution flow in mind:
Notice that there are helper methods for managing the internal list of objects (see CGenericSensor::appendObservation).
Class Factory: This is also a factory of derived classes, through the static method CGenericSensor::createSensor

This method must be called by derived classes to enqueue a new observation in the list to be returned by getObservations.
Passed objects must be created in dynamic memory and a smart pointer passed. Example of creation:
If several observations are passed at once in the vector, they'll be considered as a block regarding the grabbing decimation factor.

Typically the user may want to create a smart pointer around the returned pointer, whis is made with:
