+We want to create a function that will add numbers together when called in succession.
+
+add(1).(2);
+// returns 3
+We also want to be able to continue to add numbers to our chain.
+
+add(1).(2).(3); // 6
+add(1).(2).(3).(4); // 10
+add(1).(2).(3).(4).(5); // 15
+and so on.
+
+A single call should return the number passed in.
+
+add(1); // 1
+We should be able to store the returned values and reuse them.
+
+var addTwo = add(2);
+addTwo; // 2
+addTwo + 5; // 7
+addTwo(3); // 5
+addTwo(3).(5); // 10
+We can assume any number being passed in will be valid whole number.
