 Currently, it doesn't have a whole lot of features, but I'll be adding more in the future. Here's currently what it can do:
 - Graph an equation (duh).
     - There are currently some rendering issues with asymptotes which will be focused on at some point.
+- Integrate and derive equations.
 - Graph a slope field of a `dy/dx =` style equation.
 - View a tangent line of an equation.
 - Display a vertical bar graph.
