/*
General outline of spell casting process
1.
a) Client clicks a spell bar gem, ability, or item. client_process.cpp
gets the op and calls CastSpell() with all the relevant info including
cast time.
b) NPC does CastSpell() from AI
2.
a) CastSpell() determines there is a cast time and sets some state keeping
flags to be used to check the progress of casting and finish it later.
b) CastSpell() sees there's no cast time, and calls CastedSpellFinished()
Go to step 4.
3.
SpellProcess() notices that the spell casting timer which was set by
CastSpell() is expired, and calls CastedSpellFinished()
4.
CastedSpellFinished() checks some timed spell specific things, like
wether to interrupt or not, due to movement or melee. If successful
SpellFinished() is called.
5.
SpellFinished() checks some things like LoS, reagents, target and
figures out what's going to get hit by this spell based on its type.
6.
a) Single target spell, SpellOnTarget() is called.
b) AE spell, Entity::AESpell() is called.
c) Group spell, Group::CastGroupSpell()/SpellOnTarget() is called as
needed.
7.
SpellOnTarget() may or may not call SpellEffect() to cause effects to
the target
8.
If this was timed, CastedSpellFinished() will restore the client's
spell bar gems.
Most user code should call CastSpell(), with a 0 casting time if needed,
and not SpellFinished().
