Adrian Schlatter 315d3b96fb Release 0.3 
Enhancements
===========

- Unified Inch Screw Threads

Fixes
===========

- PCO-1881 internal (minor diameter was too small)
- Dpitch problem with G-ext threads

Improvements
===========

- developer docs
- build system
- unit tests
- user does not need to rotate internal threads by 180 deg anymore
to fit external thread

!! Incompatibel changes !!
====================

We take the liberty to do this while the major version is still 0:

- internal thread is rotated by 180 deg (see improvements). nut() and bolt() are not affected by this
