 * \ingroup propagation
 *
 *  \brief The Hybrid-Building-Propagation-Model is a compound of different models able to evaluate the pathloss from 200 to 2600 MHz, in different environments and with buildings (i.e., indoor and outdoor communications).
 *
 *  This model includes Hata model, COST231, ITU-R P.1411 (short range
 *  communications), ITU-R P.1238 (indoor communications). 
 *  Building-Propagation-Model properly combines the models above in order
 *  to be able to evaluate the pathloss under different scenarios, in detail:
 *  - Environments: urban, suburban, open-areas;
 *  - frequency: from 200 uo to 2600 MHz
 *  - short range communications vs long range communications
 *  - Node position respect to buildings: indoor, outdoor and hybrid (indoor <-> outdoor)
 *  - Building penetretation loss
 *  - floors, etc...
 *
 *  Frequency: 200 MHz to 2000 MHz
 *  Link Distance:up to 20 km
 *  Short/long distance commutation: 1 Km
 *  \warning This model works with BuildingsMobilityModel
 *
