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

Finished the example for BayesInf for the user guide and fixed some small bugs for MCMC with a single input.
Started working on the user guide for BMC, but issue in AL with changes in the model

Moved AL into SeqDesign and restructured score combination

See merge request !30

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

example_analytical_function_testSequential runs through all the sequential options and contains notes on which do not work.
Choose_next sample now uses only one set of candidate samples
