abstract: '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.'
