v0.0.9

Major refactor of the toolbox in preparation for v.0.1

Now uses the ADCP as a DVL for dive averaged currents estimations.
Uses displacement through to regress shear bias rather than variance at depth.
Modified structure of options arguments.

v0.0.7

Functional code but not fully tested or streamlined. ipynotebooks provide incomplete guidance.
Use at your own risk for now.
