11class Fragment(object):
12   """Generates HTML fragment for a declaration. Multiple strategies are
13   combined to generate the output for a single declaration, allowing the
14   user to customise the output by choosing a set of strategies. This follows
15   the Strategy design pattern.
16   
17   The key concept of this class is the format* methods. Any
18   class derived from Strategy that overrides one of the format methods
19   will have that method called by the Summary and Detail formatters when
20   they visit that ASG type. Summary and Detail maintain a list of
21   Strategies, and a list for each ASG type.
22    
23   For example, when Strategy.Summary visits a Function object, it calls
24   the formatFunction method on all Strategys registed with
25   SummaryFormatter that implemented that method. Each of these format
26   methods returns a string, which may contain a TD tag to create a new
27   column.
28
29   An important point to note is that only Strategies which override a
30   particular format method are called - if that format method is not
31   overridden then it is not called for that declaration type.
