Request: move decimal package out of internal

[whereswaldon]

The fact that decimal is in a internal directory means it's impossible for application code in consuming projects to construct *ledger.Transactions at runtime (except by parsing a string representation of them). This makes it hard to build a tool capable of authoring new transactions. Is there a reason that decimal must live in internal?

Regardless, thanks for the great work on this package!

That's a good point I didn't think about. I made it internal because it's not "general purpose" and quite specific for use within ledger.

You're right though, it should be available enough to be used if anyone wants to interface with the ledger package.

Thank you!
