  "Description": "Simulates cyclic voltammetry, linear-sweep voltammetry\n(both with and without stirring of the solution), and\nsingle-pulse and double-pulse chronoamperometry and\nchronocoulometry experiments using the implicit finite\ndifference method outlined in Gosser (1993, ISBN:\n9781560810261) and in Brown (2015)\n<doi:10.1021/acs.jchemed.5b00225>. Additional functions provide\nways to display and to examine the results of these\nsimulations. The primary purpose of this package is to provide\ntools for use in courses in analytical chemistry.",
