Description

In thinking about what I'd want a useful print method for a Dataset in R to include, there are a few things that come to mind, and by skimming dataset.h, they're not available:

• How many Sources it has
• For a Source, what kind (local filesystem, other filesystem, etc.), base path (at least where we didn't provide a list of files), how many files, what file format
