Split of MetaModel into MetaModel and PCE/GPE classes

Split the MetaModel class into a parent and child classes. The parent class contains all needed properties and functions so that the rest of the package works, while the child classes contain surrogate-type specific functionalities.

added Meta-modeling Restructuring Test labels

requested review from @mariafer.morales

assigned to @RKohlhaas

To merge this we should finish the following:

• Test that the model-comparison runs through
• Add unit tests for the GPE, goal is >60% coverage
• Test sequential design with GPE
• Test sequential design with PCE
• Use the new PCE class in the examples instead of the MetaModel class
• Update the diagrams in the docs
• Update the code descriptions in the docs
• Remove the gaussian_process_emulator from supplementary.py and rerun the tests
