- handles basic operations, references to other dictionary entries
(with '$name' syntax) and assorted mathematical functions:
pi(), degToRad, radToDeg, asin, acos, atan, sin, cos, tan, log,
log10, mag, atan2, pow
The basic syntax: #calc{ ... };
NOTE the trailing ';' is required for the primitiveEntry to be
properly defined.
