The options dialog holds all the options for the application categorized into notebook tab pages outlined
below.
The 'Cancel' button closes the dialog without implementing any of the options changes.
The 'OK' button implements the changes and updates the open views to reflect the change.
The 'Reset Defaults' button resets ALL the options to their original setting. On Exiting the program the
option state is saved to a configuration file (if the 'Save Configuration' option is checked). Using the 'Reset
Defaults' button and then exiting the program means the program will start up in its default state.
