+/*
+Write a function that takes a string of braces, and determines if the order of the braces is valid. It should return true if the string is valid, and false if it's invalid.
+
+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: ()[]{}.
+
+What is considered Valid?
+A string of braces is considered valid if all braces are matched with the correct brace.
+
+Examples
+"(){}[]"   =>  True
+"([{}])"   =>  True
+"(}"       =>  False
+"[(])"     =>  False
+"[({})](]" =>  False
