0035  * @section grammar The Grammar
0036  *
0037  * The grammar looks like this:
0038  *
0039  * Formula =: Operand | ScalarOperator Operand<br/>
0040  * Operand =: number | Field Ref | operator <br/>
0041  * Field Ref =: ${[A-z[A-z|0-9]+}<br/>
0042  * Operator =: [abs | min | max | floor | ceil | avg](Formula[,Formula]*)
0043  * ScalarOperator =: [x,-,*,/]<br/>
0044  * number =: [0-9]+<br/>
0045  * Word =: [A-z]+<br/>
