use fuzzy name comparision

use fuzzy name comparision

Sometimes, it's hard to type the correct name, (e.g. missing an "s" or
forgetting the prefix "GM:"), so I think this change would help developers a
little bit. :)

Please review, if it's OK, please help land this CL.

Agreed that this is a pain point.

Personally, I'd rather have SampleApp exit early on a mistyped argument (exiting
in line 715). Or we could look into having it list the names of pages it knows?
Right now naming is a bit odd with the GMs shoehorned in...

Exiting in class's constructor is kind of pain, we don't use try-catch block in
our current code base. So I'd prefer to add another option "--list" to list all
the names. Please review!
