2*B(bv1&bv2) / (B(bv1) + B(bv2))
C++ signature:
    DiceSimilarity(ExplicitBitVect bv1, std::string pkl, bool returnDistance=0) -> double

return the Dice similarity between two vectors
C++ signature:
    DiceSimilarity(RDKit::SparseIntVect<int> siv1, RDKit::SparseIntVect<int> siv2, bool returnDistance=False, double bounds=0.0) -> double

return the Dice similarity between two vectors
C++ signature:
    DiceSimilarity(RDKit::SparseIntVect<long long> siv1, RDKit::SparseIntVect<long long> siv2, bool returnDistance=False, double bounds=0.0) -> double

Implements the DICE similarity metric.

>>> v1 = DataStructs.IntSparseIntVect(10)
>>> v2 = DataStructs.IntSparseIntVect(10)
>>> v1.UpdateFromSequence((1,2,3))
>>> v2.UpdateFromSequence((1,2,3))
>>> DiceSimilarity(v1,v2)
1.0

>>> v2 = DataStructs.IntSparseIntVect(10)
>>> v2.UpdateFromSequence((5,6))
>>> DiceSimilarity(v1,v2)
