Simple O2 script to show Roslyn's Ast Error detection capabilities

Here is an simple O2 script that shows Roslyn's C# AST parsing capabilities in action, including how to show squiggly lines in the source code on the locations of those errors.

Note how fast the whole process is, and how Roslyn is able to handle broken C# files (my plan is to use this inside O2's REPL environment in order to give much better error messages when the AST is broken)
