Clean Up

Fixed grammar issues
In Flight manager I added comments to the interface and to the
implementation
I changed a few little things in the constructor but i did not delete
anything i just commented things out. If you do not like it you can
change it. I put a question in flightmanager cpp on line 106, can some
some please explain that to me.
Also i think we should all put comments in our cpp files; I know chetlen
would like that, also it is good note keeping for ourselves when we look
back at this later on. If you guys do not like the comments i made you
can change them.
