Profiling

A memory profiling of the parameter-framework has been performed using Valgrind's Massif tool while running the Getting started tutorial. Here is the corresponding visualization:

Obtained using:

 valgrind --tool=massif --time-unit=ms --detailed-freq=1 --depth=100 test-platform ~/pfw_example ParameterFrameworkConfiguration.xml & sleep 0.4; sh ../../pfw_example/run_tuto.sh 

run_tuto.sh contains:
