Minimum level a headline must have before it is treated as an inline task.
Don't set it to something higher than 29 or clocking will break since this
is the hardcoded maximum number of stars org-clock-sum will work with.
It is strongly recommended that you set org-cycle-max-level not at all,
or to a number smaller than this one. In fact, when org-cycle-max-level is
not set, it will be assumed to be one less than the value of smaller than
the value of this variable.
