looks at the contents of the file to determine what keys would be used to map the the values when the file is being parse. It looks for comma and pipe characters and default to space delimiters. Note: this works on the assumption that each file wont have delimiter characters of another file like "greg, | thomas"

gets the contents of a file from the given path and turns it into a string. Note: this assumes small files sizes as the application would become much more complex when considering file piping for large files

get the file paths from the arguments given at the command line

This is a application specific function and is the only one meant to be used outside of testing. It works by

1. getting the paths from the parameters
2. taking each path and a) getting the string from the contents of the file b) getting order of the keys should be parsed in from the file type c) using results from both a and b to parse the file string into user models d) doing light validation on each user model

takes a given delimited string and an array of mapping properties to parse out the user data
