Working file store with caching to the disk.  It stores files in the File entity and referes to them by hash.  element_answers and applicant/anser attachments can just sotre the hash and we do not ever need to pull the file unless it is requested.
Migration up/down capable with no data loss.
Replaced the globals sesssion file manager with file store methods so we can easily secure user files by thier hash.
Created a console command to seed the file cache by thier lastAccessed date.
Optomized the Array and DisplayArray Applicant hydrations to just use the hash and not the complete file.
