[SPARK-10906][MLlib] More efficient SparseMatrix.equals
@jkbradley
Calls toBreeze.activeIterator which, for CSCMatrix, returns an iterator
with only non zero values. The iterators are then converted to sets and
checked for equality. Since the input parameter can be of type DenseMatrix
the second set is filtered for non-zero values. This is because
activeIterator
for DenseMatrix returns all values.
