New parser

[abourget]

Hi :) Not really an issue, but wanted to let you know I've written a Ledger parser in Go, which generates a nice AST: https://github.com/abourget/ledger

Tell me what you think :)

Very interesting. I applaud the effort to attempt parity with the original C++ tool. I'll be interested to see the finished product and any other tools that may be built on top.

Keep at it, looks neat!
