Examples of org.openquark.cal.metadata.CALExpression

org.openquark.cal.metadata.CALExpression
CALExpression models an expression in CAL, similar to what would be entered into the code gem in the GemCutter. In this version the expression is assumed to have no free variables i.e. the code gem would have 0 arguments.
Sample expressions:
```
 [10.0, 20.0, 30.0] take 10 allPrimes Prelude.ones \x y -> sqrt (x * x - y * y) 
```
