Looping over optimization runs (within a model, batch executions, and multiple models/submodel)

Description

This example shows different possibilities of looping over a series of optimization runs using different data sets.

In the first case (batch1.mos) the loop is implemented within a single Mosel model. At every loop execution a new data set is read and the model is redefined correspondingly.
The second model (batch2.mos) only defines and solves once the optimization problem. It is run either from a batch file (runbatch2), or from an application using the Mosel Libraries (batch2.c), or as a submodel from a second Mosel model (runbatch2.mos) and receives the name of the data set to be used through a runtime parameter.
