    44== 1) Demystifying the addMeasurement method ==
    55'''addMeasurement in Application definition''' :
    6 Application definition is created by the application developer. The application developer chooses what measurements will be generated by the application, how they will be grouped and what name to give to the measurement group. An experimenter has no control over this. This is the "WHAT" of measurement collection. The application writer decides what measurements will be generated by the application.

The application developer chooses what measurements(metrics) will be generated by the application, how they will be grouped and what name to give to the measurement group. An experimenter has no control over this. This is the ''"WHAT"'' of measurement collection since the application writer decides ''what'' measurements (metrics) will be generated by the application.

    2121'''addMeasurement in Prototype definition''' :
    22 As an experimenter you read what measurements are available to you in a particular application. The application definition has the comprehensive list of measurement groups and the metrics listed within each group.
    23 The experimenter controls which measurements to use in the experiment and how to process them or filter them, via a prototype. He or she can use one of the predefined prototypes  or create their own. Think of the prototypes as the "Avatars" that you define to control the "HOW" of measurement collection i.e. HOW often the measurements will be aggregated and which of them you are interested in and how you want to filter them.
