checkSequence() updated to recognize different representation of tiebreak points
checkSequence() updated to recognize different representation of tiebreak points

match.push() now recognizes when a tiebreak point is being pushed such
that it can support match.push(‘1-1’) as well as match.push(‘1T-1T’)
and match.push([0,1,1,0])
more robust sequence checking.
