**
** \brief A custom ANTLR input stream that reads from the input stream lazily
**
** By default, ANTLR expects the whole input to be in a single, consecutive
** buffer. When doing incremental solving and the input is coming from the
** standard input, this is problematic because CVC4 might receive new input
** based on the result of solving the existing input.
**
** This file overwrites the _LA and the consume functions of the input streamto
** achieve that and stores the lines received so far in a LineBuffer.
