- I. Now have a class (SETTINGS) and GUI (pair_dlg) to load and adjust
SEV defaults.
-   A.  Added  CLASS_settings: A class for handling global initialization and settings
    1.  Load settings
    2.  Save settings -> imported saveParametersToFile.m as a method
    3.  Interface for editing the settings
 - B. Improve SEV GUI so I can have all of the defaults placed somewhere.
    1. Adjust sampling rate of viewer -> occurs in the settings now
    2. added CLASS_settings.m to handle settings of the SEV
    3. updated CLASS_UI_marking.m to include instantation of CLASS_settings as a property
    4. created gui pair_value_dlg to edit such structs of default values.

- II.  Refactored code
 -  A.  menu_analyzer -> menu_tools : renamed Analyzer to Tools in menubar
 -  B.  menu_preferences -> menu_settings: renamed Preferences to Settings in Menubar
 -  C.  Moved timeline selection from Settings to Tools (was not hooked in before).
 -  D.  moved loadStruct.m to a static method of CLASS_settings
 -  E.  move loadParametersFile.m to a static method of CLASS_settings
 -  F.  folded STATE (previously a global struct) into CLASS_UI_settings
 -  G.  changed obj.sev to obj.SETTINGS.VIEW
 -  H.  changed name of several CLASS_ files which used "_events_" or "_event_" to try and be consistent.
