Add examples of how to use

[Balaji Pokuri]

Examples should be of

• test functions ( 2 or 3 )
• function evaluators:
  • in-script ( 1 )
  • out-of-script ( 1 )
  • asynchronocity with fractional required fraction ( 1 )
• changing kernel functions / acquisition functions
  • example of derived function class for kernel ( 1 ) (after resolving issue #15)
• kriging and optimal sampling (1 or 2 )
• visualization

These should further serve as a means to test the functionality of the optimization in case of

• extension with other optimizers
• additional features

Very important for open-source repository

Also need an example of how to import data.

All the examples are included, not individually but collectively. Only multiple test functions are not presented, but this is not a major concern.
