anchor.diff:  Just double the letters: +##+ and +$$+
   
   Exemple:
  -
  -  #template renderAccount(int account, int amount)
  -    Account ##$(account) owns $(amount)$$
  -  #end
  +--------------------------------------
  +#template renderAccount(int account, int amount)
  +  Account ##$(account) owns $(amount)$$
  +#end

positive.code: The minimum: define a rendering method in your template
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
    #template renderHello()
      Hello World
    #end
  
  - +#template+ defines a new rendering funtion.
  - +myrenderfunction+ is the name of the method to be called from your Java code.
  
negative.code: Fields and methods can be defined on the template class. It is just regular Java.
  
  Exemple:
  --------------------------------------
  import java.io.File
  
  private File path;
  
  private void setPath(File path) {
    this.path = path;
  }
  
  #template renderPath()
    $(path.getAbsolutePath())
  #end
