// MANIPULATION TREE
//
// Abilities in this tree allow the AI to physically manipulate systems around the station.
// T1 - Electrical Pulse - Sends out pulse that breaks some lights and sometimes even APCs. This can actually break the AI's APC so be careful!
// T2 - Hack Camera - Allows the AI to hack a camera. Deactivated areas may be reactivated, and functional cameras can be upgraded.
// T3 - Emergency Forcefield - Allows the AI to project 1 tile forcefield that blocks movement and air flow. Forcefield´dissipates over time. It is also very susceptible to energetic weaponry.
// T4 - Machine Overload - Detonates machine of choice in a minor explosion. Two of these are usually enough to kill or K/O someone.
