ptysh 0.1.0

## PTYSH
PTYSH is an abbreviation of 'Python Teletype Shell'.<br>
It was made with reference to the 'zebra vtysh'.<br>
Vtysh is an integrated shell for Quagga routing software.<br>

Ptysh is not the only route shell, the shell is customizable, so you can normally use.<br>
It made it possible to add commands to the module for availability.<br>
