JOB POINTS
----------
      JP are doled out according to this equation:

JP = [(8 + (JobLevel * 2) + [Lv / 4]) * M]

where JobLevel is caster's level at their current job
           (can range from 1 - 8)
      Lv is the level of the person performing the action
      M is 3/2 if the caster has 'Gained JP-UP'
           1 otherwise

JP SHARING When unit X gains JP, everyone else in the party will earn
[gained JP / 4] towards the job which unit X currently has. Note: if
unit X has 'Gained JP-UP', the extra JP given by that ability are
ignored in the JP sharing equation.

Monsters do not receive JP.
