Created generic file string reader, pom mainclass

- Created a generic file reader using the read file's name as a key
in a HashMap.
- Updated pom.xml to have the main class specified so java -jar works
without having to specify the main class
Removing unnecessary logging

A little too much logging - changed to only log when it reads from
a file.
