Detailed Description

template<class PositionPolicy, class VelocityPolicy, class AnglePolicy, class SizePolicy, class ColorPolicy, class AgePolicy, class UserPolicy = NullInitPolicy<Particle>, class ParticleType = Particle>
class InitPolicy< PositionPolicy, VelocityPolicy, AnglePolicy, SizePolicy, ColorPolicy, AgePolicy, UserPolicy, ParticleType >

The complete Policy template for initializing particles, used by the ParticleSystem class.

Template Parameters:

	PositionPolicy	the policy for updating particle position, expected to have the same methods as the Policy template.
	VelocityPolicy	the policy for updating particle velocity, expected to have the same methods as the Policy template.
	AnglePolicy	the policy for updating particle angle and angular velocity, expected to have the same methods as the Policy template.
	SizePolicy	the policy for updating particle size, expected to have the same methods as the Policy template.
	ColorPolicy	the policy for updating particle color, expected to have the same methods as the Policy template.
	AgePolicy	the policy for updating particle age, expected to have the same methods as the Policy template.
	UserPolict	an extra policy that can do whatever the user wants. Defaults to the NullPolicy.
	ParticleType	the type of particle to use in the particle system. The ParticleType is expected to inheret from the Particle class (or at least have duplicate members).
