Description: Given a time series or pseudo-times series of gene
        expression data, we might wish to know: Do the changes in gene
        expression in these data exhibit directionality?  Are there
        turning points in this directionality.  Do different subsets of
        the data move in different directions?  This package uses
        spherical geometry to probe these sorts of questions.  In
        particular, if we are looking at (say) the first n dimensions
        of the PCA of gene expression, directionality can be detected
        as the clustering of points on the (n-1)-dimensional sphere.
