Battery-less Capacitor-based IoT nodes in ns-3

This is an ns-3 code including

• the implementation of battery-less capacitor-based IoT nodes
• the implementation of an Energy-Harvesting source taking as input traces provided by the user
• an updated version of the lorawan ns-3 module employed to obtain simulations of a LoRaWAN network with battery-less capacitor-based end devices.

In the current version, original contribution include:

• Capacitor Energy Source
• Variable Energy Harvester
• Integration of the new components in the existing lorawan module

To avoid compilation errors, in ns3/src/energy/model/energy-source.h, the private variables should be moved to protected.
