/*
New Easy Experience Build:
Determine PCs via:
    Controlled by a player
    Settings Config menu: - done (except for pet)
        Active
        MIA
        Pet - Maybe
            Link to Master Char via level formula (e.g. level, level-1, or level/2) - Maybe/maybe not

Continue using Thresholds character for storing of session xp and thresholds
    Add custom XP track capability - done
        probably simply dynamic handling of number of levels on thresholds character, character created with custom number of levels.
    Add handling for modifying thresholds character instead of requring manual deletion - done

Discontinue use of State for storing progressions, simply load at creation. - done

Add handling for undefined, null defined, or empty experience/level attributes
