INCOMPLETE TrimFile

// Needs to be abstracted further, currently hardcoded to output TrimmedFile to Console
// limitation: how big should the buffer be? (right now hard coding is the most efficient?)
// does the semantic of just getting one line, then displaying to Console out, really use less memory?
// TODO: fix the "do one thing" , Object should have getFile , trimFile , displayTrimFile
// requires CommandLineParams.java
