+## exports
+
+###reader
+reader exports four customized functions that affect arrays
+####reader.readFile
+takes in an array of paths and a callback function, and returns an array stringified files. it also catches errors and returns a descriptive error message
+####reader.readFiles
+takes in an array of paths and a callback function, and returns an array stringified files. it also catches errors and returns a descriptive error message. The files will stay arranged as they come in because of the recursive nature of the function.
+#### NOTES
+I am now in the process of refactoring to recursive functions and fixing my original functionality. The readFiles function is structured like the one during code review, I intend to improve on my testing.
