Initializing help system before first use

# xpress.ctrl

Purpose

Internal object class used for the controls of an xpress.problem. The user can read and write controls for a problem, but cannot create objects of this class.

Example
The following example creates a problem and then reads and sets a few of its controls:

    import xpress as xp

    p = xp.problem()

    x = [p.addVariable() for _ in range(10)]

    p.addConstraint(xp.Sum(x) >= 1)

    print('miprelstop is currently", p.controls.miprelstop)

    p.controls.miprelstop = 1e-7
    p.controls.xslp_solver = 0

    # An equivalent way to do the two lines above
    p.setControl({'miprelstop': 1e-7, 'xslp_solver': 0})
