Example LP_LPCreation (H169E3)

We create an LP representing a problem in 2 real variables:

> R := RealField( );
> L := LPProcess(R, 2);
> L;
LP <Real Field, 2 variables>
Minimising objective function: [0 0]
Subject to constraints:
Variables bounded above by: [ ]
Variables bounded below by: [ ]
Solving in integers for variables [ ]
