Decide on ordering for Gang of Four equations and plots
Issue #60
resolved
In various places in the text we have all four of the Gang of Four transfer functions, but we seem to use different ordering in different places. Some examples:
 When we define the sensitivity functions in Chapter 12 (page 123), we give a 2x2 matrix of transfer functions in the following order (left to right, then top to bottom): S & PS \\ T & CS (note that this is the first place they are defined and it might make sense to list S and T in the first column, even if it is inconsistent with other uses)
 In Example 12.1 (page 125) we list them as T & PS \\ CS & S
 In Figure 12.10 (page 1217) we plot the gang of four in the order S & PS \\ CS & T
 In Figure 12.22 (page 1231) we plot the gang of four in the order S & PS \\ CS & T (this comes from the custom MATLAB function gangof4)
 In Chapter 13 in the section on the Youla parameterization (page 1314), we list the functions as a single row: S, PS, CS, T
 On the next page we lay these out in a matrix: S & PS \\ CS & T
 In Example 13.11 we plot the Gang of Four in Figure 13.13 (page 1320): the order is S & PS \\ CS & T
 In Figure 13.14 (page 1322) the order is S & PS \\ CS & T
 In Figure 14.13 (page 1425) the order is S & PS \\ CS & T
From these, it appears that the outlier is the original definition on page 123 (which I think is probably OK) and Example 12.1 on page 125.

All plots are now consistent: S, PS \ CS, T.

Updated Example 12.1 to be consistent with the other examples (and MATLAB function) in commit 43dbd23. Leaving this in place to confirm this is OK with Karl.
