Add Goals you want to check for completion

myset.add("job1").add("job2")
myset.size
#=> 2

Check if all the goals are completed

myset.met?
#=> false

Get the unmet Goals

myset.unmet
#=> [...]

Get the met Goals

myset.met
#=> [...]

Iterate all Goals

myset.each {|goal| ...}
myset.map  {|goal| ...}
