/**
* Returns the activity associated with the given layout file.
*
* <p>This is an alternative to {@link #guessActivity(IFile, String)}. Whereas guessActivity
* simply looks for references to "R.layout.foo", this method searches for all usages of
* Activity#setContentView(int), and for each match it looks up the corresponding call text (such
* as "setContentView(R.layout.foo)"). From this it uses a regexp to pull out "foo" from this, and
* stores the association that layout "foo" is associated with the activity class that contained
* the setContentView call.
*
* <p>This has two potential advantages:
*
* <ol>
* <li>It can be faster. We do the reference search -once-, and we've built a map of all the
* layout-to-activity mappings which we can then immediately look up other layouts for,
* which is particularly useful at startup when we have to compute the layout activity
* associations to populate the theme choosers.
* <li>It can be more accurate. Just because an activity references an "R.layout.foo" field
* doesn't mean it's setting it as a content view.
* </ol>
*
* However, this second advantage is also its chief problem. There are some common code constructs
* which means that the associated layout is not explicitly referenced in a direct setContentView
* call; on a couple of sample projects I tested I found patterns like for example
* "setContentView(v)" where "v" had been computed earlier. Therefore, for now we're going to
* stick with the more general approach of just looking up each field when needed. We're keeping
* the code around, though statically compiled out with the "if (false)" construct below in case
* we revisit this.
*
* @param layoutFile the layout whose activity we want to look up
* @return the activity name
