Create an assessment directory

I've been doing a few take-home assessment recently, all of which I've attempted
to solve using Haskell. I'm having a good time, and I'm noticing strong and weak
points with my Haskell programming. I always attempt to apply any feedback a
reviewer gives me, and I'm storing my first drafts, second attempts, and
feedback here for now.

This recently attempt was for a role at Jane Street.

+# Dotted Squares
+
+This is my second attempt at solving this problem. I had an hour to solve it the
+first time, and I unfortunately came up short although I made good progress.
+
+The problem asks to read input from a text file that looks like this:
+
+```
+1     -- board width
+1     -- board height
+4     -- number of lines of "moves" (below)
+0 0 R -- create a unit vector (0,0) facing right
+0 0 U -- create a unit vector (0,0) facing up
+0 1 L -- create a unit vector (0,1) facing left
+1 1 D -- create a unit vector (1,1) facing down
+```
+
+After parsing and validating the input, score the outcome a game where players
+one and two alternatively take turns drawing lines on a board. Anytime one of
+the players draws a line that creates a square from existing lines, they get a
+point.
