/**
 * Mailchimp HTML Apps Script Library
 *
 * A Google Apps Script Library to generate the HTML for MailChimp.
 *
 * Called from within the template file. Example:
 *
 * `<? var data = getData('All Tools!A2:K31'); ?>`
 *
 * where `All Tools!A2:K31` defines the Sheet name with a header column
 * named "Scheduled for". Specify the optional second parameter if that field
 * name is different.
 *
 * Returns an array of rows that are selected for publication. Key names are the
 * header columns.
 *
