Release v0.2.0

0.2.0 (2020-10-05)

This is a minor version with bug fixes, new features, and documentation improvements.

Note: Figure theme (.figtheme) files saved with the plotting gui in versions < 0.2.0
will not be compatible with versions >= 0.2.0.

• FEATURE: Allow marking and labelling peaks in the plotting gui.

• FEATURE: File searching is more flexible, allowing for different numbers
  of samples and files for each dataset.

• FEATURE: The window location for the plotting gui is maintained when
  reopening the window.

• FEATURE: The json files (previous_search.json and the figure theme files saved
  by the plotting gui) now have indentation, making them more easily read and edited.

• FEATURE: Figure theme files for the plotting gui now contain a single
  dictionary with all relevant sections as keys. This allows expanding the data
  saved to the file in later versions without making breaking changes.

• FEATURE: Allow selecting which characterization techniques are used when
  generating raw data.

• FIX: Changed the Excel start row sent to user-defined functions by adding 2 (to allow
  for the header and subheader rows). Now formulas can directly use the start row variable,
  rather than having to manually add 2 each time. Changed the use_main_gui.py example program
  to reflect this change.

• FIX: Changed save location for previous_search.json to an OS-dependant location, so that
  the file is not overwritten when updating the package.

• FIX: Allow doing peak fitting without saving to Excel.

• EXAMPLES: Switched from using plt.pause and a while loop to using plt.show(block=True)
  to keep the peak_fitting and generate_raw_data example programs running while the plots
  are open.

• DOC: Made all the documentation figures have the same file extension, and made
  them wider so they look better in the README where their dimensions cannot be modified.
