CompareQuartets() uses explicit enumeration to compare two lists of
quartet states, detailing how many are identical and how many are unresolved.
For most purposes, the faster function
QuartetStatus() will be preferable.
List of quartet states, perhaps generated by
Returns an array of seven numeric elements, corresponding
The total number of quartet statements for two trees of n leaves, i.e. 2 Q.
The total number of quartets for n leaves.
The number of quartets that are resolved identically in both trees.
The number of quartets that are resolved differently in each tree.
The number of quartets that are resolved in tree 1, but not in tree 2.
The number of quartets that are resolved in tree 2, but not in tree 1.
The number of quartets that are unresolved in both trees.

QuartetStatus() generates the same output from a list of trees.
