Implementation of commonly used design patterns in Go.

Although the code is self-explanatory, but still here are some tips.

• Each go package represents a design pattern.
• Each package has a README.md file which briefly describes the design pattern. It also has a problem statement which the code is trying to solve. Going through the class diagram will give a general idea of the flow of data in the code.
• Packages do not have a main() method. Instead, the objects are instantiated in the tests. So please go through tests as that is the entry point for each package.

Enter into the repo and type:

go test -v ./...

This will run all tests of every package.
