Embed ledger in another file

[vorpalvorpal]

Is your feature request related to a problem? Please describe.
It would be nice to be able to embed the ledger dashboard into another file. Bonus points, if you could select particular accounts to embed. If for example I have a page devoted to a particular supplier, it would be nice to be able to see all transactions related to that supplier at the top of the page.

Describe the solution you'd like
Some simple syntax to embed a view of the ledger dashboard
