A names list of lists:
- level one
- The name of the table layout 
- level two
- The name of the summary type required. one of - subtype_count,- median_iqr,- mean_sd,- skipped
- level three
- a named list of - column=- glue specificationpairs. The- column(itself a glue spec) might reference- N_total,- N_presentor- .unitbut typically will be a fixed string- it defines the name of the table column to generate. The- glue specificationdefines the layout of that column, and can use summary statistics as below
- subtype_count
- can use - level,- prob.0.5,- prob.0.025,- prob.0.975,- unit,- n,- N.- nis subgroup count,- Nis data count.
- median_iqr
- can use - q.0.5,- q.0.25, ...,- unit,- n,- N-- nexcludes missing,- Ndoes not.
- mean_sd
- can use - mean,- sd,- unit,- n,- N-- nexcludes missing,- Ndoes not.
- skipped
