[Clp] COIN-CLP e OSL startups correlation in ClpSimplexPrimal::primal method

[John Forrest]

Michel,

The following is approximate (just looking at recommended settings for
OSL and Clp)

ekk_setIdevexMode - the equivalent method is mode in Constructor of
ClpPrimalColumnSteepest
1 has no equivalent in Clp (I would translate as 0)
2 translates to 0
3 translates to 1

For startup mode 

0,1,2 correspond approximately to ifValuesPass=0
3 normally corresponds to ifValuesPass=1
You can use setIstopMode to make 3 correspond to ifValuesPass=2 (i.e.
stop after values pass).
