/**
 * Class MucSoftID contains the "software" representation of a MUC channel address.
 *
 * Indexing a Muc readout channel (in the "software" scheme) requires 4 numbers:
 \begin{enumerate}
 \item the part  number,              m_Part  (0-east cap, 1-barrel, 2-west cap)
 \item the seg   number in a part,    m_Seg   (barrel 0-3, cap 0-7)
 \item the gap   number in a segment, m_Gap   (barrel 0-8, cap 0-7)
 \item the strip number in a gap,     m_Strip (barrel gap 0,2,4,6,8 0-47
 \                                             barrel gap 1,3,5,7   0-95
 \                                             endcap               0-63)
 \end{enumerate}
