Changed the training samples and added BayesInf and additional models for BMC

See issue #46, voronoi exploration was removed for v1.1.0, but should be reactivated in future releases. The corresponding tests were changed accordingly.

All combinations of tradeoff-exploration-exploitation run through with SeqDesign. Reverted BayesInf to the current develop branch

Errors thrown by the tests were resolved where possible.
If they could not be resolved and issue was created for them.
For the sake of testing the pipeline, the unresolved tests were commented out.

This reverts commit acf483a1

BMC only runs the BME part of BayesInf, split JA into its own function, removed redundant function in MCMC, added to function diagrams

More test for BayesInf, starting tests for MCMC

Some simple fixes for various test, start on testing BayesInf, output directory as changeable parameter in BayesInf

Solved some issues from rebasing

OLS constraint directly to be set in the MetaModel source code. Small regression comparison as example for the constraint. No unit tests yet for the feature

In this scope the multiprocessing for running the models does not seem to work correctly anymore

Got started on these two tasks, restructuring still needs a lot of work here

New class 'Engine' responsible for both training sequentially and non-sequentially.
Currently training with old MetaModEngine and in MetaMod directly still possible, but will be deprecated and removed soon.
Also started splitting ExpDesign into InputSpace (for MetaMod, created dists and polynomials) and ExpDesign (for Engine, can also sample)

Started testing MetaModel while also refactoring a bit more by moving code between ExpDesign and MetaModel

Added tests for Inputs and started on those for ExpDesign.
Regarding the second there are some open questions noted in issue #32
