v0.3.0

• DistMatrix and SquareMatrix can optionally store a list of labels corresponding to the underlying elements (e.g. taxa). There are new methods to get values by label. Some APIs changes as a result, for example the file parsers now just return a matrix rather than a (labels, matrix) pair.
• DistMatrix and SquareMatrix can be constructed from iterators over pairs of labels associated with distances using from_labelled_distances.
