v2.0

[iboB]

It is time for v2.0 to address deficiencies in the current design.

Concrete things:

• Use C++17 this is a long way into the future, so why not...
• Allow standalone functions with first arg mixin to serve as message implementations #24
• Allow renaming of message implementations #25
• Improve exceptions #26
• Better header structure
• Improve design of public and private data for objects (no more #define internal public)
• Mixin/Message domains – sets of mixins and messages that cannot be mixed. Will throw a runtime error when trying to combine certain mixins or messages.
• Address serialization better
• Allocator extension
• Mixin class which holds information for mixin
• Get implementers for msg as mixin ids
• Allocators for absolutely everything
• Allow onMutated private message
• Compilation performance benchmarks
• Logging and debug information prints
• fuzzing
• Package managers and cmake install
• coverage
• Optimize mutation process: less allocations. Design special mixin_collection for the process, that can be preallocated (or that uses a buffer that's allocated only once) and has reserve. Allow reuse of single_object_mutator.
• Add a new mixin feature fact. Facts are static const variables in a mixin. No multicasts. No virtual tables.
• Reflection. Call messages by string.
