[Osi] rhs of tableau row with OsiClp and Clp

[Lou Hafer]

Matt,

	OsiSolverInterface::getBasics will get you the indices of the basic
varibles.  There's nothing in Osi that returns the values of the basic variables
in basis order --- you'd need to ask for the whole column solution and pick out
the basic variables.

	I take it you're looking for the latter -- values of basic variables in
a compact array in basis order?
