differential is a simple program and library for basic differential expression
analyses. The program finds the log2 fold change with Kruskal Wallis
significance. Expects an input CSV file with names (genes), statuses (e.g.
control vs. disease), and value for that name in that status (abundance). The
library includes additional methods of finding differential expression.
