Release notes

0.5.0 WIP
- Major refactoring and rewrite of the library
- Units are now independent from dimensions
- Dimensions now depend on units (base or coherent units are provided in a class template)
- Quantity gets a Dimension template parameter again (as unit does not provide information about its dimension anymore)
- Added official CGS system support
- Added official data information system support
- Repository file tree cleanup
- ratio refactored to contain Exp template parameter (thanks a lot @oschonrock!)
- SI fundamental constants added
- q_ prefix applied to all the UDLs (thanks @kwikius)
- unknown_unit renamed to unknown_coherent_unit
- Project documentation extended and switched to Sphinx
- A few more usage examples added
- Linear algebra from std::experimental::math support added
- ...
Many thanks to GitHub users @oschonrock and @kwikius for their support in drafting a new library design.
