Basic modeling tasks: data input, optimization, enumeration

Description

Simple exam scheduling problem (formulated with disequality constraints) showing basic modeling tasks:

data input from file - static arrays (i4exam_ka.mos)
data input from file - dynamic arrays (i4exam2*_ka.mos)
optimization (i4exam3_ka.mos)
definition of a branching strategy over decision variables of type cpvar (i4exam4_ka.mos)

Further explanation of this example: 'Xpress Kalis Mosel User Guide', Sections 2.2 Data input from file and 2.3 Optimization and enumeration
