1838    
1839    URL of the image to display next to the tree nodes when they are collapsed. Clicking
1840    on the image will expand a section of the tree. The default is C<../FIG/Html/plus.gif>.
1841

1843    
1844    URL of the image to display next to the tree nodes when they are expanded. Clicking
1845    on the image will collapse a section of the tree. The default is C<../FIG/Html/minus.gif>.
1846    
1847    =item style
1848    
1849    Style to use for the tree. The default is C<tree>. Because the tree style is implemented
1850    as nested lists, the key components of this style are the definitions for the C<ul> and
1851    C<li> tags. The default style file contains the following definitions.
1852    
1853        .tree ul {
1854           margin-left: 0; padding-left: 22px
1855        }

1860  =head2 Feature Column Methods  The default image is 22 pixels wide, so in the above scheme each tree level is indented from its
1861    parent by the width of the node image. This use of styles limits the things we can do in formatting
1862    the tree, but it has the advantage of vastly simplifying the tree creation.

1864  The methods in this column manage feature column data. If you want to provide the  =item name
 capability to include new types of data in feature columns, then all the changes  
 are made to this section of the source file. Technically, this should be implemented  
 using object-oriented methods, but this is simpler for non-programmers to maintain.  
 To add a new column of feature data, you must first give it a name. For example,  
 the name for the protein page link column is C<protlink>. If the column is to appear  
 in the default list of feature columns, add it to the list returned by  
 L</DefaultFeatureColumns>. Then add code to produce the column title to  
 L</FeatureColumnTitle> and code to produce its value to L</FeatureColumnValue>, and  
 everything else will happen automatically.  
1865    
1866  There is one special column name syntax for extra columns (that is, nonstandard  Field name to give to the radio buttons in the tree. The default is C<selection>.
 feature columns). If the column name begins with C<X=>, then it is presumed to be  
 an extra column. The column title is the text after the C<X=>, and its value is  
 pulled from the extra column hash.
