Get the ordering of the leaves in a dendrogram

Description:

     This function returns the order (index) for the leaves in a
     dendrogram.  These indices can then be used to access the
     appropriate components of any additional data.

Usage:

     order.dendrogram(x)

Arguments:

       x: A dendrogram (see 'as.dendrogram').

Details:

     The indices for the leaves in left to right order are retrieved.

Value:

     A vector with length equal to the number of leaves in the
     dendrogram is returned.  Each element is the index into the
     original data (from which the dendrogram was computed)
