	REMIX EXAMPLE PROJECT

	Remix example project is present when Remix loads very first time or there are no files existing in the File Explorer.
	It contains 3 directories:

	1. 'contracts': Holds three contracts with different complexity level, denoted with number prefix in file name.
	2. 'scripts': Holds two scripts to deploy a contract. It is explained below.
	3. 'tests': Contains one test file for 'Ballot' contract with unit tests in Solidity.
