-====== Messenger ======
-Frequently there is a need to communicate with People with same interests or located in the same area. Examples:
-  * a hotel guest might want to discover groups of the hotel
-  * at some event men want to organize Minyan and want a way to agree on time and place
-  * a lost child or item was found and want to announce that in "Lost and Found" group of the area
-  * a person wants to discuss some public event with like-minders
-For matter of the Machon Tal Term Project Success, the POC would allow flow below:
-  - A person creates "stored query" with properties below:
-      * kind: Messages
-      * with date not older than week ago
-      * geo: X,Y with radius R
-      * query lifetime for the next 2 hours
-  - He reviews results and sees summary of Messages found, grouped by topic name and number of unique posters (implying activity) and wants to subscribe to certain topic:
-      * he creates folder with "chat view" Memo with the topic id, and exports it
-      * the Memo automatically creates "stored query" for Memos of kind:Message, date not older than week ago and that topic id
-      * any message Memo he creates will contain same topic id, and get consumed by other subscribers
-      * he might want to enable popup notification on every incoming message
-The scenario above might be extended to cover more cases like these:
-  * ignore someone that posts offensive content
-  * send message about group details to someone ("Invite them")
-  * propose "group" icon that allows voting. The one with most votes is shown as "group" logo
-===== Privacy (aka Mail mode) =====
-There might be need to for private Memos exchange between two or more parties. For many-to-many communcations, single shared pubkey is created, per the flow below:
-  - An public/private keypair is created
-  - For each recipient, it is encrypted with his public key and Memo of kind "KeyPair" and recipient id is created
-  - Recipients has active subscription to all Memos of kind "KeyPair" and recipient equals his id
-  - recipient receives the "KeyPair" Memo, decrypts it and stores in his keyring.
-  - recipient subscribes to all Memo of kind "Encrypted" and id=hashed keyring
-  - All messages shared in the folder are encrypted using the keyring
