Detailed Description

holds etiss::instr::Instruction instances and handles automatic instruction tree creation.

 Location in an instruction translation tree:
    ModedInstructionSet
        ↳ VariableInstructionSet (e.g. for mode 0)
            ↳ InstructionSet (e.g. 32 bit)
                ↳ Instruction (e.g. LDR, STR)
            ↳ InstructionSet (e.g. 16 bit)
