metaData

[rgentlem]

I think this is a useful function - but it needs to be described more accurately.
Somewhere in the phonto package we have to be clear that it relies on the Docker container.
And hence the SQL database. Then we need to describe the metadata tables and then finally
you could explain why this function is useful

You might also want to contrast it with the newly created nhanesManifest function.

I wonder if we don't need a vignette that helps to describe the whole NHANES (CCB version) project

Description
It shows NAHANES medata such as, tables, variables and codebooks.

Usage
metaData(meta)
