anyToken :: Parser Char
```
This combinator should read and return exactly one character from the input.
If the character does not match the given character, then it should fail.
```haskell
token :: Char -> Parser ()
```
This combinator should read a string of charracters. If the string does not match the given string then fail.
```haskell
tokens :: String -> Parser ()
```
This character reads any number of consecutive characters, which stisfy the predicate. So this can never fail.
```haskell
tokensWhile :: (Char -> Bool) -> Parser String
```
This character reads any number (but at least one) of consecutive characters, which stisfy the predicate. This can only fail if the first character does not satisfy the predicate.
```haskell
tokensWhile1 :: (Char -> Bool) -> Parser String
```
