	 * Base class for all scripts. Includes virtual methods to be overridden to handle LUA equivelent events.
	 * 
	 * All methods pass 'self' as the first parameter, this is the associated parent entity for the event.
	 * There will only ever be one instance of each script.
	 * 
	 * Do not use class members as entity specific variables unless you're sure there will only event be one instance of this script.
	 * Do use class members as script wide variables, variables all entities which this script will access.
	 * 
	 * Use self->GetVar<type_t>(u"variable_name") and self->SetVar<type_t>(u"variable_name", value) to manage variables.
	 * 
	 * Designed to yield as close to a 1:1 mapping as possible with LUA.
	 * There will be events which are not implemented or inheritetly LUA features not easily translated to C++.
	 * Most of the time these can be worked around or ignored.
