[Coin-lpsolver] Requests from INFORMS

[John J Forrest]

I have put up a first draft of a "C" interface to Clp.  The header file is 
Clp/include/Clp_C_Interface.h.  The functions available are a subset of 
the ones in ClpModel.hpp and ClpSimplex.hpp and are the most useful for a 
user.  There is a sample program in Samples called driverC.c with 
Makefile.driverC.  I will now look at callbacks in C.

I have added an extra  void pointer in ClpModel.hpp to give any user a 
useful pointer.

I have added a secondary status value to say that the scaled problem was 
feasible but that unscaling introduces infeasibilities.  That way the user 
can clean up by scaling(0) and then primal() or dual().

I have submitted some pages of notes and an explanation of common messages 
to Robin.  When she has got me to improve it that will be posted.
