* New visualisation Samplevis visualises sample data files.
  (Note: visualisations are currently stored in the package, but
  are not available via FDSTools commands yet. A new tool is going
  to be introduced later, which will copy the visualisation files
  to a user-selected folder.)
* Including the current versions of Vega and D3 for completeness.
* Fixed missing numpy dependency in setup.py.
* Clarified some option help texts in Allelefinder based on
  feedback by Rick and Kris.
