Generates mixed integer rounding cuts.
Another mixed integer rounding cut generator, CglMixedIntegerRounding, is very similar.
CglMixedIntegerRounding uses CoinPackedVector whereas CglMixedIntegerRounding2 uses CoinIndexedVector.
Depending on the size of the problem, one generator might be faster than the other.
