Milestone_3_Automating the data-analysis pipeline using Make

[zouwenjiao]

Write another script, a Makefile (literally called Makefile), to act as a driver script to rule them all.

This script should run the others in sequence, hard coding in the appropriate arguments.

This script should:

• live in the project's root directory and be named Makefile
• be well documented (using the project README and comments inside the Makefile to explain what it does and how to use it)
• have a all: target so that you can easily run the entire analysis from top to bottom by running make all at the command line
• have a clean: target so that you can easily "undo" your analysis by running make clean at the command line
