Wellpathpy

Features
* deviation_to_csv transposes before writing.
* devation and position have learnt how to print in the repl.

Fixes
* The position log and deviation no longer crash on straight hole conditions.
* Vector angles are computed with a more numerically stable method.
* Deprecation warnings for numpy type aliases are addressed.

==========
* The minimum_curvature.resample() method has been fixed and resamples the arc correctly

=============

This is the first release of wellpathpy! Please note that even though this is a proper release, the API is not stable, and can still change.

Highlights
-------------
* Easy reading of deviation surveys from file with read_csv
* Easy computation of well paths with deviation.minimum_curvature()
* Compute deviation surveys from position logs with position_log.deviation()
* Easy unit conversion
