Sept 30: Two important errors to fix

I must fix two important details in the assignment specification. I've amended the comments in A1Driver.java

The file format of the file containing the list of points tells you that there will be one point on each line. What it does not tell you is that each of the values on a line should be separated by a space.

The get method is not clear in how the points should be ordered. They should be ordered by increasing distance from the view point.

Sept 27: samePlane

The description of samePlane was not sufficiently clear. If the dimension number is k and the viewpoint has value p in dimension k then you want to find all other points whose value in dimension k equals p.

For example, if the viewpoint is at (3, 5, 2), and we call samePlane(0), then samePlane will print all points whose value in the 0th dimension is 3 -- e.g., (3, 2, 4).

Sept 27: Equation

I goofed on the equation in the handout, so I've changed it. The absolute value calculation is wrong, and because of the square, unnecessary. Make sure you can handle negative numbers in the coordinate space.
