 * @dtf.author Rodney Gomes
 * 
 * @dtf.tag.desc Divide op1 by op2 and store the result in the property
 *               identified by the attribute result. Dividing by zero will 
 *               generate an ArithmeticException that can easily be caught in 
 *               your DTF test using the {@dtf.link try} and ${@dtf.link catch}
 *               tags.
 * 
 * @dtf.tag.example 
 * <divide op1="100" op2="${proerty1}" result="result"/> 
 *
 * @dtf.tag.example 
 * <divide op1="${a}" op2="1000" result="a"/>
