/** This program demonstrates how to write a transformer that turns Frink
expressions into something that you can cut-and-paste into Java code.
Instead of UnitMath, you may change this to something like BigInteger or
BigDecimal.
At the moment, this doesn't turn Frink's square brackets into Java's
parentheses, though.
