class fennel::Calculator

Detailed Description

Base class for all extended instructions.

ExtendedInstructions allow a programmer to extend Calculator with greater ease than adding regular instructions. See ExtendedInstructionHowTo for details.

Derived classes are typically (though not necessarily) templates such as ExtendedInstruction1.
