A few test changes...

To see how you all like them... more on the way...

* ``.touchs``... why is it called "touchs" and not "touches"? I changed it to "touches".

* Some of the double if statements were turned into a single if statement.

* Cosmetic changes to make the code more readable, like converting single-statement if statements from 3 lines to 1, and standardizing if statements to:
````
if (a) {
    x;
}
if (a) x;
````

VS:


if(a) {
    x;
}
if(a)x;
````
