virtual unsigned NxsCharactersBlock::GetNumObsStates ( unsigned  columnIndex,
bool  countMissingStates = true 
) [inline, virtual]
the number of states observed in a column If `countMissingStates` is true then missing data is treated as an observation of each state. If it is false then missing codes do not contribute to the count. Partially ambiguous states result in all states in the cell being counted as observed.

columnIndex should be in [0, nchar)

{If countMissingStates is true then it a gap as a state, if countMissingStates is false the the gap will count as a state if the gapmode is GAP_MODE_NEWSTATE}
