Is Alliant Steel a double base or a single base propellant and what exactly does that mean? Thanks

A simple Google search.
Single based
Smokeless propellant powder which has colloided nitrocellulose as its main ingredient, and contains no other major energy-producing component
Double based
propellants generally contain a nitrocellulose type of gun powder dissolved in nitroglycerine with additional amounts of minor additives.

To my knowledge, within the realm of North American pistol/shotshell powders there are no current single base powders. The FBI's data shows Steel to contain nitroglycerine, making it double base. See the "List of components".
Alliant Steel is definitely a double base smokeless powder. It means that it is made with both nitrocellulose and nitroglycerin. The nitroglycerin adds some energy and also stabilizes the nitrocellulose.
As Silver_Is_Money stated there are no currently US made shotshell powders that are single base.
There are quite a few European single base powders, meaning they are made using nitrocellulose only, with no nitroglycerin.
In real world application the difference between the two types of powder is tiny. The difference is you will generally use less of the double base powder, to get the same job done, however there are a lot of ifs and buts in that statement.
I kinda like the single base powders best, mostly because I have used a lot of the old DuPont powders, but I use plenty of double base powders, Steel being one of them.
