-### SpearAssist
-- Boost Modes:
-  - Dash - While charging with your right click you can boost yourself forward a specific distance with your left click creating a velocity based attack.
-  - Hold - While charging you are constantly boosting forward whenever you press the left click.
-- Your player can optionally stay grounded when boosting as to avoid flying off into the distance on each attack.
-- Highlighting: You can highlight near and far entities within your attack range. Near meaning the distance you can jab at them and far the distance you can charge at them. Default set to 7 for near and 8.5 blocks for far.
-- Your charge is automatically and constantly resumed (no cooldown) so you can forever hold right click. It will be noisy but even if the spear is pointed down you will still be able to attack. 
-- You can optionally allow aim assist to work whilst holding right click.
-- Auto Attack, your jab attack will continue to auto hit once the cooldown has expired so long as you're hitting an entity.
-- Designed for elytra-free ground PvP/PvE, though may be even more interesting with one.
