 * Class NF_Updates_CacheCollateForms
 * 
 * This class manages the step process of running through the CacheCollateForms required update.
 * It will define an object to pull data from (if necessary) to pick back up if exited early.
 * It will run an upgrade function to alter the nf3_forms and nf3_form_meta tables.
 * Then, it will step over each form on the site, following this process:
 * - New columns in the nf3_forms table will be populated with data from the cache.
 * - New and existing columns in the nf3_form_meta tables will be populated from the cache.
 * - A new record of the cache will be saved to the nf3_upgrades table (if it does not already exist).
 * After completing the above for every form on the site, it will remove the data object that manages its location.
