+//The above is just to create a general/barebone structure
+//of the code.  This is just to build something, so that
+//I can see the "main page" of todoCLI.js asking a user to
+//choose from the v, n, cX, dX and q options.
+
+/**
+ * MY  PROPOSED  ALGORITHM - Nov 23, 2018
+ * step 1 - create a general/barebone structure to show the 
+ *          interface as soon as todoCLI.js is run in the terminal.
+ * step 2 - In the callback function of rl.question(), call 
+ *          another function called "userInput".
+ * step 3 - In this "userInput" function, there will be various "if...else" statements
+ *          responsible for the available choices.  
+ *          I expect to use the following methods for each option:
+ *          view -->  fs.readFile, rl.close()
+ *          new -->   fs.writeFile, rl.close()
+ *          complete->fs.writeFile, rl.close()
+ *          delete--> fs.unlink, rl.close()
+ *          quit -->  rl.close()

+ /** Nov 25, 2018
+  * I realized I started coding for the "stretch" homework.
+  * So, I decided to rewrite my code for the "non-stretch" homework first.
+  * I will tackle the "stretch" homework later.
+  * 
+  * 
+  * 
+  ** Nov 30, 2018
+  *  I cleaned up my code by deleting unneccesary comments and empty spaces.
+  *  I cleaned up my code by indenting properly.
+  *  I cleaned up my code by naming my variable with meaningful word choices.
