This Kata is similar to the Valid Parentheses Kata, but introduces new characters: brackets [], and curly braces {}. Thanks to @arnedag for the idea!
All input strings will be nonempty, and will only consist of parentheses, brackets and curly braces: ()[]{}.
A string of braces is considered valid if all braces are matched with the correct brace.
"(){}[]" => True
"([{}])" => True
"(}" => False
"[(])" => False
"[({})](]" => False
