0.0.16 "Pine Cobble"

This version of readgssi (called Pine Cobble) fixes the colormap which previously reversed polarity (issue #18), as well as command line control of DPI, fixes the sampling frequency calculations using epsr (epsilon sub r or relative permittivity) for user-specified epsr, and other small fixes. Significantly, this version adds full documentation, hosted at https://readgssi.readthedocs.org/ (issue #9).

Version 0.0.16 "Pine Cobble" continues the naming scheme based on names of mountain peaks in the Williamstown, Massachusetts area.

changes since 0.0.15

• fixed #14 which incorrectly asserted that user-set samples per meter was negative when it was not (sign was flipped) but processed the file correctly regardless
• moved zoom calculation and automatic file naming to their own functions
• added sphinx autodoc descriptions to some functions, in order to work towards solving #9
• added comments to datetime parsing function
• fixed sampling frequency calculations to the value of epsr set in the header, which will prevent perceived frequency wander in frequency-based filters if the user sets epsr
• changed the behavior of the readdzt script to automatically search for a DZG file of the same name, and load that data if possible. this should allow python users to read all three variables (header, arrays, gps) if GPS exists.
• fixed command line control of DPI
• switched to "gray" colormap from "Greys". "Greys" rendered opposite polarity #18
