figuring out how all of this stuff works, still very confused on where
to include javascript files and how to access the code through all the
modules

- replace the code with html for people can click buttons and fill out
fields! they won’t need to see any data/code.js files!

Allowing for custom node positions on graphs

CONTRIBUTORS.md

Can add custom (x,y) positions for all the nodes in a graph!  This code
doesn’t not work or effect the graphs that are “trees” i.e using
setTreeData.

Shortest Common Supersequence algorithm  

Updated setup_top_menu.js 

added color customization

The coders are able to set the tracer’s colors to anything they want!
Since I use the style background color attribute on the div it can
accept a wide variety of values for the background color.

I first wanted to pass in some color value when calling notify or
select but then I realized there is a lot of issues with the amount of
parameters . So I thought of doing some sort of global set like the
HTML canvas/context does.

Tracer now has 5 new methods for setting the colors.
_Set(name)FillColor(color_goes_here).

The logic of the setting fillColor and it being displayed should be
similar to the canvas/context fillStyle setting. It will keep using
that color until the color is switched again.

I had to change the clear method inside array2d.js also to handle the
new coloring change.
