The code tflplanner writes where a report says none: the company
standards' sheet code_templates (see company_standards()).
table_data takes a table's rows of the study ARD, table_process
normalizes them (and shows where to rework them), figure_plot is the
plot a figure starts with, setup the code every report of a new study
runs first. In a template, {OUTPUT_ID}, {ARD} (the study ARD),
{ARD_PROGRAM} (the output's ARD program), {PROGRAM} and {STUDY_ID}
stand for the report's.
