LRDOCS 436, formatting--Chapter 4-Theme Development-->Task begun, concurrent with wordsmithing.  Unfinished.
LRDOCS340, wordsmithing Chapter 4-->Chapter Completed. Portal Predefined Settings section was confusing, perhaps because of my lack of development background.
LRDOCS 436, formatting--Chapter 4-Theme Development-->Added topics list to introduction.  Used the sections beginning with ## to populate topic list. Removed Figure 4.3 (picture of theme directory structure, which we'd just listed in detail), since it was too close to Figure 4.4.  Left figure 4.6 and 4.7 since 4.7 is very small.
LRDOCS340, wordsmithing Chapter 4-->Worked a little more on predefined settings section.
