Create a distance matrix from a numeric Metadata column
#######################################################

Create a distance matrix from a numeric metadata column. The Euclidean
distance is computed between each pair of samples or features in the
column.  Tip: the distance matrix produced by this method can be used as
input to the Mantel test available in `q2-diversity`.

Parameters
----------
metadata : MetadataColumn[Numeric]
    Numeric metadata column to compute pairwise Euclidean distances from

Returns
-------
distance_matrix : DistanceMatrix
