     /**
35 |  |
      * MapBuilder is used during the parsing/building phase of a template to create
36 |  |
      * user defined Map types, using a syntax that is similar to:<pre>
37 |  |
      *     #set $map = { "key" => "value", "key2" => "value2" }
38 |  |
      * </pre>
39 |  |
      *
40 |  |
      * MapBuilder ultimately creates a Map that understands <code>org.webmacro.Macro</code>'s
41 |  |
      * for <i>keys</i> and <i>values</i>, so $Variable references are okay for both.
