look-up tables to eliminate all caps, notation that each
district is an elementary district, and to expand
abbreviations. The names have not been thouroughly
double-checked.

Data set is complete
Horizontal_Positional_Accuracy_Report:
Approximate horizontal accuracy is 51 meters, assuming
source data meets National Map Accuracy Standards.
