| A Stream of characters fed to the lexer from a InputStream that can
be rewound via mark()/rewind() methods.
A dynamic array is used to buffer up all the input characters. Normally,
"k" characters are stored in the buffer. More characters may be stored during
guess mode (testing syntactic predicate), or when LT(i>k) is referenced.
Consumption of characters is deferred. In other words, reading the next
character is not done by conume(), but deferred until needed by LA or LT.
