<commit_before># steinlang

### Demo

There's no lexing/parsing yet, but there are some example programs in the `lang/interpreter/pgms` subdirectory which are ASCII protobuf syntax trees.

It's possible to write new syntax trees, but it's a pain in the buns.

The `interpreter_main` binary can evaluate them, print any output printed by the program, and print some timing information.
To build:
```
$ mkdir build && cd build
$ cmake ..
$ make
$ cd lang/interpreter
$ ./interpreter_main.exe --input_file=pgms/fibo_test.txt
