/**
 * BlockMacro directive is used to invoke Velocity macros with normal parameters and a macro body.
 * 
 * The macro can then refer to the passed body AST. This directive can be used as a 
 * "decorator". Body AST can contain any valid Velocity syntax.
 *
 * An example:
 * 
 * #set($foobar = "yeah!")
 * 
 * #macro(strong $txt)
 * <strong>$bodyContent</strong> $txt
 * #end
 *
 * #@strong($foobar)
 * <u>This text is underlined and bold</u>
 * #end
 * 
 * Will print:
 *  * <strong><u>This text is underlined and bold<u></strong> yeah!
 * 
 * 
 * bodyContent reference name is configurable (see velocity.properties).
