EnergyProfile.java: Added a profile for energy usage for an elevator car.

TimeProfile.java: Added a profile for time usage for an elevator car.

The time profile will be changed in the future to have better physical meaning.
For not, it uses getEnergyH() function to determine the time values for traveling
certain amount of floors. Note that this is not be realistic.

For all profiles, the units are discrete (natural/integer numbers).
