/// This class implements a level scheme. The level scheme has a
/// vector of bands/groups of levels. Each of the bands contains
/// a map of levels, and each level has a map of gamma rays draining it.
/// The gamma rays can have strength assigned to them which then
/// can translate to the width of their arrows.
