====== Full_ADDER Class ======
FULL_ADDER Class implements a working full adder circuit for use in the CPU Simulator
===== FULL_ADDER() Constructor =====
<code c++> FULL_ADDER myFullAdder; </code>

^ Function ^ Parameter(s) ^ Return Value |
| FULL_ADDER() | none | instantiation of newly allocated FULL_ADDER object |

FULL_ADDER() is the parameterless constructor that is responsible for creating a new instance of a FULL_ADDER circuit.

===== set(bool, bool, bool) =====
Takes 3 parameters and sets a, b, and carryI to those values. The sum is then achieved by sending a and b as inputs into an xor gate. The result of this first xor gate and the carry in are then used as input into a second xor gate. The sum is the result of the second xor gate.

Now the carry out is calculated. The carry out is achieved by first sending a and b as inputs to an xor gate. The result of the xor and the carry in are then sent, as inputs, to an and gate. a and b are also used as inputs to another and gate. The results of the two and gates are then used as inputs to an or gate, which outputs the carry out.

<code c++> myFullAdder.set(true, true, true); </code>

^ Function ^ Parameter(s) ^ Return Value |
|void set() | bool, bool, bool | none |

===== getSum() =====
Returns 1 of the two outputs of the full adder, the sum. 

<code c++> myFullAdder.getSum(); </code>

^ Function ^ Parameter(s) ^ Return Value |
|bool getSum() | none | bool |

===== getCarryOut =====
Returns 1 of the two outputs of the full adder, the carry out. 
<code c++> myFullAdder.getCarryOut() </code>

^ Function ^ Parameter(s) ^ Return Value |
|bool getCarryOut() | none | bool |
