Changes to the model selection print out.

Fix for the setUp() method. The 'palmer' data pipe shouldn't be created!

Used the new model_type() specific method to differentiate between global and local models.

Removed the model_index arg from model_type().

Activated the specific model_type() method.

Created the model_type() method to determine whether the model is local or global.

Renamed the duplicate_data() arg model_info to model_index.

Fix for the determination of the global_stats flag in model_statistics().

Converted the rest of the model selection to the model_loop() design.

The following model-free methods have been converted to using the model_loop():
duplicate_data()
model_statistics()
skip_function()

Shifted to the use of the model_loop().
