Sage Server

Functionality:

• keep track of list of running sage processes, with some info about them (total memory, time)

• write that list periodically to somewhere in the database (about this project), so can be shown to users

• start a sage process

• stop/kill a sage process

• interrupt a sage process

• evaluate a block of code (with data) and push out results as they appear

• maintain queue of evaluation requests

• if sage server likely to be started (based on previous usage of this project), start it right when project starts up
