Grub is the bootloader - so the purpose of editing it is to change parameters during boot.
The files you can edit are /etc/default/grub and the scripts in /etc/grub.d.
Changing the grub.cfg in /boot/grub is not recommended as any changes you make manually will be overwritten the next time an update to grub is called.
If there is a specific reason that you want to edit the file please update your question.
GRUB:= GRand Unified Boot-loader
It is a common boot loader that can boot the system, weather Linux or windows or others Grub Editing= play with the boot configuration or customize the boot configurations.
How to edit : as said in forestpiskie's post you can manually edit those files.. or use a GUI for that...
Grub customizer is a good one ( look :Grub Customizer installation) Startup manager is also fine (check : community website )
BUT IF YOU MANAGE TO MESS UP WITH BOOT, You can't boot into the system... don't worry a lot of methods are there to fix the boot loader.....
The recommended one is Boot Repair....Boot repair installation it can fix the problem even if the boot loader is deleted or corrupted...... Also keep the copy of boot repairer disk (check:Boot-repair disk Source forge page) before you attempt some thing that may corrupt the loader...
If you wanted to customize the GRUB too badly... read this manual
If you want to theme grub your own reading the book listed in this post may help you :grub guide by Towheed Mohammed
All the best with grub editing and customizing... if for info hope that this provides necessary information.. if not ask :)
