class Hash
# Returns a hash that includes everything except given keys.
# hash = { a: true, b: false, c: nil }
# hash.except(:c) # => { a: true, b: false }
# hash.except(:a, :b) # => { c: nil }
# hash # => { a: true, b: false, c: nil }

# This is useful for limiting a set of parameters to everything but a few known toggles:
# @person.update(params[:person].except(:admin))

# Removes the given keys from hash and returns it.
