• added the possibility to register free functions for constructors
• the variant class has get comparison operators == and <
• the variannt_array class is replaced by variant_array_view class
• added the possibility to register default values to methods and constructors
• added the possibilities to register names of method parameters
• new policies for constructors were added
• it's now possible to invoke methods while the instance is in a wrapped type, like std::shared_ptr<T>
• a lot of refactoring internally, almost every class was internally refactored
• added several benchmarks to measure the performance impact from certain
  API calls of the library
• adjusted documentation style to use cleaner and modern HTML5 style
• rewritten the tutorial
• switched from mercurial to git and uploaded the source code to github
