/**
 * Extension for adding up points in an assignment.
 *
 * No more need to stress that point totals don't add up!! 😰
 *
 * Defines one role:
 *
 *   - `points` displays points and records number in total
 *
 * And one directives:

This past week, I worked on implementing the H-J formulation of Maxwell's equations (in the Frequency Domain) in simpegEM. So for this week's journal, I thought I would write about the 4 different approaches we have implemented for solving the FDEM problem.
