*
* 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.
