# Validate all keys in a hash match *valid keys, raising JactiveSupport::InvalidParameter on a mismatch.
# Note that keys are NOT treated indifferently, meaning if you use strings for keys but assert symbols
# as keys, this will fail.
#
# ==== Examples
# { :name => "Rob", :years => "28" }.assert_valid_params(:name, :age) # => raises "InvalidParameter: Unknown key(s): years"
# { :name => "Rob", :age => "28" }.assert_valid_params("name", "age") # => raises "InvalidParameter: Unknown key(s): name, age"
# { :name => "Rob", :age => "28" }.assert_valid_params(:name, :age) # => passes, raises nothing
