[Coin-lpsolver] Running sample5.cpp

[svoboda at fi.muni.cz]

I've compiled ../COIN/Cbc/Samples/sample5.cpp
There are some strange constructions I do not understand:

- Where are the definitions of macros COIN_USE_CLP and COIN_USE_OSL?

- What is OSL? I do understand OSI - as an interface, but OSL?

- Why is the code forked into two alternatives using either CoinBuild or 
CoinModel? What is the main difference?
