v0.5.0

Hyperopt v0.5.0

• Breaking: The Hyperband macrobody now gets the amount of resources as a floating-point value rather than floored to an integer.
• Breaking: The GPSampler has been removed. It was hard to maintain and never worked very well. Consider using the new BOHB instead.
• New sampler BOHB curtesy of @noilreed . See the instructions.
• hyperband now has an interface that takes a function and a vector.
• New function hyperoptim performing multi-start optimization with Optim and Hyperband. The interface is similar to that of Optim.optimize, but the initial guess is replaced by a vector of candidate vectors. This function is only available after using Optim.
• New function warn_on_boundary: Prints a warning message for each parameter where the optimum was obtained on an extreme point of the sampled space.
