v0.3

Third time's a charm.

New features

• Accuracy improvements of the optimization of the acquisition function
  by pre-selecting good candidates as starting points when
  using acq_optimizer='lbfgs'.
• Support a ask-and-tell interface. Check out the Optimizer class if you need
  fine grained control over the iterations.
• Parallelize L-BFGS minimization runs over the acquisition function.
• Implement weighted hamming distance kernel for problems with only categorical dimensions.
• New acquisition function gp_hedge that probabilistically chooses one of EI, PI
  or LCB at every iteration depending upon the cumulative gain.

Bug fixes

• Warnings are now raised if a point is chosen as the candidate optimum multiple
  times.
• Infinite gradients that were raised in the kernel gradient computation are
  now fixed.
• Integer dimensions are now normalized to [0, 1] internally in gp_minimize.

API Changes.

• The default acq_optimizer function has changed from "auto" to "lbfgs"
  in gp_minimize.
