/// One object of this class is created for each BCAL electronic
/// channel. The objects are created once at program start up and
/// certain values filled in that exist for the life of the object.
///
/// The uphits and downhits containers are cleared at the start of 
/// each event and filled as the s_BcalSiPMUpHit_t and s_BcalSiPMDownHit_t
/// structs are created in the HDDM tree.
///
/// The s_BcalfADCUpHit_t and s_BcalfADCDownHit_t structs are made
/// later using the uphits and downhits. The value of NSiPM
/// is used to hold how many SiPMs are being added together for
/// this readout channel. The number of channels to generate dark
/// hits for the readout channel is calculated from:
///
/// Ndark_channels_up   = NSiPM - uphits.size();
/// Ndark_channels_down = NSiPM - downhits.size();
///
/// This is susceptable to a problem when more than one s_BcalSiPMUpHit_t
/// is generated for a given cell and they are not properly separated 
/// into multiple s_BcalfADCUpHit_t structs.
///
/// The value for <i>threshold</i> is calculated once at program startup
/// based on whether this is an "inner" or an "outer" cell. It is applied
/// to all summed energy values before creating a s_BcalfADCUpHit_t struct
/// (or a s_BcalfADCDownHit_t).
