ARM model data file names should match model name

[mitzimorris]

most ARM model files have corresponding data.R files, but not all -
e.g. model ARM/Ch.3/kidiq_validation.stan has 2 data files:

• kids_before1987.data.R
• kids_after1987.data.R

these should be renamed so that initial name matches model name, e.g.
kidiq_validation_pre1987.data.R, etc.

We can code missing data in Stan---see the manual chapter. It's not trivial, but it's also not impossible.

made copies of existing data files w/ names that matches model it matches.
the following models don't seem to have data:

ARM/Ch.17/multilevel_poisson_17.5.stan  - (traffic stop data?)
ARM/Ch.17/multilevel_ordered_categorical_17.6.stan 
ARM/Ch.21/finite_populations.stan
ARM/Ch.21/multiple_comparison.stan
ARM/Ch.19/item_response.stan
ARM/Ch.25/earnings2.stan
ARM/Ch.25/earnings_pt2.stan
ARM/Ch.25/earnings.stan
ARM/Ch.25/earnings_pt1.stan
