    Embedded provides easy means to embed JellyEngine and use Jelly scripts within an application

    A typical usage: 

     
     Embedded embedded = new Embedded();
     embedded.setOutputStream(new ByteArrayOutputStream());
     embedded.setVariable("some-var","some-object");
     .....
     embedded.setScript(scriptAsString);
     //or one can do.
     //embedded.setScript(scriptAsInputStream);

     boolean bStatus=embedded.execute();
     if(!bStatus) //if error
     {
         String errorMsg=embedded.getErrorMsg();
     }
