=head2 Tree Rewriting Methods
+=head3 $elem->hashmap($attr_name, \%hashref, \@excluded, $debug)
+
+This method is designed to take a hashref and populate a series of elements. For example:
+
+
+ <table>
+ <tr sclass="tr" class="alt" align="left" valign="top">
+ <td smap="people_id">1</td>
+ <td smap="phone">(877) 255-3239</td>
+ <td smap="password">*********</td>
+ </tr>
+ </table>
+
+In the table above, there are several attributes named C<< smap >>. If we have a hashref whose keys are the same:
+
+ my %data = (people_id => 888, phone => '444-4444', password => 'dont-you-dare-render');
+
+Then a single API call allows us to populate the HTML while excluding those ones we dont:
+
+ $tree->hashmap('sid' => \%data, ['password']);
+
+
+Note: the other way to prevent rendering some of the hash mapping is to not give that element the attr
+you plan to use for hash mapping.
+
+Also note: the function C<< hashmap >> has a simple easy-to-type API. Interally, it calls C<< hash_map >>
+(which has a more verbose keyword calling API). Thus, the above call to C<hashmap()> results in this call:
+
+ $tree->hash_map(hash => \%data, to_attr => 'sid', excluding => ['password']);
+
+
=head3 $elem->replace_content(@new_elem)
Replaces all of C<$elem>'s content with C<@new_elem>.

C<iter()> was fine for awhile, but some things
(e.g. definition lists) need a more general function to make them easy to

-=head2 Tree-Building Methods: Select Unrolling
+
+
+=head3 Select Unrolling
The C<unroll_select> method has this API:
option_selected => $closure, # boolean to decide if SELECTED
data => $data # the data to be put into the SELECT
data_iter => $closure # the thing that will get a row of data
+ debug => $boolean,
+ append => $boolean, # remove the sample <OPTION> data or append?
);
Here's an example:
option_content => sub { my $row = shift; $row->clan_name },
option_selected => sub { my $row = shift; $row->selected },
data => \@query_results,
- data_iter => sub { my $data = shift; $data->next }
- )
+ data_iter => sub { my $data = shift; $data->next },
+ append => 0,
+ debug => 0
+ );
