Demonstrates SHA256 hashing. Shows a basic proof of work example as well.

                	        tally += 1

	        if tally == DIF:
        		break

	timestamp = str(datetime.now())

	print(timestamp,DIF,x,d)

Example output, shows a hash of the word "hello"
Then it applies a nonce appended to hello to get hashes with zeros at the beginning, simulating proof of work for an example.
Shows timestamps to show how long it takes to generate the hashes as the difficulty rises.
