Lazy evaluation for Formula.java
Travis from the dev list suggested a speed improvement for formula evaluation
by reducing the number of byte to object and object to byte conversions
performed in o.a.p.ss.formula.Formula.
We can use lazy evaluation here to avoid unused conversions between byte[]
encodedBytes and Ptg[] ptgs.
