[om-list] use cases: choose type, edit property, delete property, delete entity

[Luke Call]

[Obviously these need work.]

*****choose type ["basic"/atomic, or object/class thing]
*****edit property
******when you change an entity (add/edit/del attrib or relat) that the 
system could/should ask the user if the same change applies to objects 
"like this one" (probably those that have been initially formed in its 
image, possibly those that it was formed like, or optionally those in a 
class that the user can define by query, list, etc) [same goes for 
add/delete property or relationship; same for delete object or create 
relationship or anything else?]
*****delete property
*****delete object
