/** This should be a description of what this Affector does and where it might be used
 * This description will show up in the online html documentation files. Even though it takes
 * a couple minutes, it pays to do a decent job in these descriptions because the exact
 * use for an Affector is the kind of thing you are likely to forget.
 *
 * The next section of this comments should show the formula being used. The third and fourth
 * sections of this comments should contain a short description of each
 * node or parameter used by the Affector, and an example of what the Affector would look like
 * in a network file. We do the parameters section using a table, which makes it easier to
 * read - if you don't know html, just make one copy of the line that starts with <tr> for
 * each parameter and replace ANode with the parameter name and Describe node here with the
 * parameters description.
