C$++$ Proxy objects$>$

Modify Proxy.h and Proxy.cpp to add proxy objects

$1.$ Due to the improved optimization ability of the compiler$($Some restrictions apply...$)$

$2.$ You cannot implement the following function in the header, you should be implementing the appropriate proxy with $5$ vectors.

Vect$2$D operator $+($const Vect$2$D &tmp$)$ const;

$3.$ Data needs to stay private. You cannot make it public

$4.$ You $\_$CAN$\_$ do work in the header for your proxies
