/**
* dynamicedit.js
*
* Shared code, data, and functions for the dynamic add/remove lists on the
* edit group/user pages.
*
* These functions have specific expectations of the page they are used on:
*
* - If you want to preserve the dn_to_info_hash on round trip:
* - The form must have a 'form_dn_to_info_json' hidden field.
* - The form must have onsubmit="preSubmit()" set in its tag.
* - Restoring the contents of add/remove lists on round trip unfortunately
* can't be shared because it is a mixture of python and javascript. See
* the bottom part editgroup.kid for example code on this.
*
* - The page must have a div: 'newmembers'
* that new members are dynamically added to.
*
* - The page must have a div: 'delmembers'
* that removed members are dynamically added to.
*
* - Hidden fields called 'dnadd' and 'dndel' will be dynamically created,
* holding the values of the 'dn' passed to addmember() and removemember()
*
* Other Notes:
*
* - Many of the fields refer to 'dn'. There is no intrinsic reason this has
* to be a dn (it can hold any "unique id" for the objects to add/remove)
*
* - Similarly, the word 'member' is used because the code was originally
* written for editgroup. A 'member' is just a 'thing' to add/remove.
* On the useredit pages, for example, a 'member' is actually a group.
