 The guts of sanitized is it's convert method, it will converts strings into their approprate types.
 It tries to convert strings in the following order, trying the next thing if it fails or returning
 the new value if it succeeds
 
     Boolean: Saneitized.convert('true') #=> true ('false' works the same way)
+    nil:     Saneitized.convert('null') #=> nil  (also converts 'nil' and 'NULL')
     Integer: Saneitized.convert('42') #=> 42
     Float:   Saneitized.convert('22.2') #=> 22.2
     JSON:    Saneitized.convert("{\"hello\":\"goodbye\"}") #=> {"hello"=>"goodbye"}
     Time:    Saneitized.convert("2014-05-28T23:15:26Z") #=> 2014-05-28 23:15:26 UTC
