Principal Coordinate Analysis
###############################################################

Apply principal coordinate analysis.

Parameters
----------
distance_matrix : DistanceMatrix
    The distance matrix on which PCoA should be computed.
number_of_dimensions : Int % Range(1, None), optional
    Dimensions to reduce the distance matrix to. This number determines how
    many eigenvectors and eigenvalues are returned,and influences the
    choice of algorithm used to compute them. By default, uses the default
    eigendecomposition method, SciPy's eigh, which computes all
    eigenvectors and eigenvalues in an exact manner. For very large
    matrices, this is expected to be slow. If a value is specified for this
    parameter, then the fast, heuristic eigendecomposition algorithm fsvd
    is used, which only computes and returns the number of dimensions
    specified, but suffers some degree of accuracy loss, the magnitude of
    which varies across different datasets.

Returns
-------
pcoa : PCoAResults
    The resulting PCoA matrix.
