[ GSoC 2019 ] [ Phase 1 ] Project: 7 years later, On vector<bool>

[JeanHeyd Meneide]

Dear libstdc++,

     I have finished Phase 1 of my GSoC 2019 project.

     An in-depth, friendly writeup can be found here:
https://thephd.github.io/std-byte-me-gsoc-2019

     In accordance with my proposal, I have:

   - implemented all of P0237 - https://wg21.link/p0237
   - stretch goal met: implement const_bit_iterator as well as iterator,
   and const_bit_reference as well as bit_reference for improved handling of
   const-correctness in non-mutable ranges
   - implemented bit_view<T> (called bitset_view<T> in the proposal)
   - implemented dynamic_bitset<T> after investigating the interface
   requirements (currently, SequenceContainer is required)
   - stretch goal met: implemented a mutable, but non-resizable range
   bit_span<T>

     The code is contained in this repository here, that I will work on
submitting proper patches to libstdc++ once I finished Phase 2, which is
algorithm optimization for std::rotate, std::find, and more:

     Do let me know if you have any questions!

     Thank you for your time, help, and patience in helping me get
bootstrapped and going with this.

Sincerely,
JeanHeyd "ThePhD" Meneide
