fixes #902 and #901 here are the functions which @carolrose wrote with some of my guidance :) now they will be availible in everyone's corpus so that if they want to, they can also use the cleaning example to make their own cleaning examples. eventually if people use these we can make data lists in the app that the user can interact with, without having to be a power user. like having a perpetual list of data taht should be cleaned for animicy etc... ask @hisakonog for details
