usage: pairem2 [filename] error added

BufferedReaders for subclass main functions added as well
Added more file stufff
Lets just use the pairPeople.java file

I fixed most of it. Added a bunch of code. Got the syntax right. I get
an initialization error for person.java though, and I tried to manually
initialize name, age, gender, title but that didnt fix it. Download the
pairPeople.java and the pairPackage folder. Should be compilable
