A computer game like Strip Poker written in golang. This program uses a deck of cards for studying gambling or probability.
Instead of hand coding each card with text string into a map, this will help to create the cards on the fly into a slice and
want to shuffle the cards as well.

1. Deal the card
2. Shuffle the deck
3. Save the deck in the file stored on harddisk
4. Create new deck from the file

This program is written in golang using OOPs paradigm design. Although, Go doesn’t it but Go has types and methods and allows
an object-oriented style of programming, there is no type hierarchy. The concept of “interface” in Go provides a
different approach that we believe is easy to use and in some ways more general. There are also ways to embed types in other
types to provide something analogous — but not identical — to subclassing. Moreover, methods in Go are more general than in
C++ or Java: they can be defined for any sort of data, even built-in types such as plain, “unboxed” integers. They are not
restricted to structs (classes).
