//! The interface for an interleaved layer.
/*!
    This class is only here to support older (pre 2.0) BAGs that have an optional
    layer of NODE or ELEVATION group type.
    In 2.0, these "interleaved" layers are split up into layers of each type in
    the group.
    The NODE group is made of Hypothesis_Strength and Num_Hypotheses.
    The ELEVATION group is made of Shoal_Elevation, Std_Dev and Num_Soundings.
