Format of the coordinate matrix (Coords) in ALEX.

    The built-in "Analyze" functions of ALEX, as well as the
        extra functions written in the Bustamante Lab, store the
        coordinates of measured molecules and any calculated
        parameters in a global matrix called Coords. Coords is a
        N-by-4 matrix of the following format:

    The first column of Coords contains an identifier specifying the
        type of coordinate or parameter on that row:

        Identifier        Type

        0            Measure lines
        1            Raw DNA coordinates
        2            Smoothed DNA coordinates
        3            Lengths
        4            Reserved
        5            Reserved
        6            Angles
        7            Reserved

    NOTE: Any extra function using Coords cannot use the above identifier
        numbers as something else. Please define other numbers for
        different measurements or parameters.

    Coords(1,1) contains the molecule counter - the number of molecules
        measured so far.

    Coords(:,2:4) contain either the x,y,z coordinates of the points of
        the molecules or the parameters as [param 0 0].

    Molecules are delineated by a row consisting of: NaN NaN NaN NaN . A
        "molecule" in Coords is then a series of points plus any
        parameters (lengths, angles, etc.) associated with those
        points.

    All coordinates and lengths are stored in nanometers, and all angles
        are stored in degrees.
