fix old particle removal

keep track of time since simulation start

ArrayRef take_front and take_back methods

pass elapsed seconds into step function

automatically initialize attributes the emitter does not care about

method to fill an ArrayRef

emitter can decide which attributes it initializes

introduce concept of particle block slices

fix lazy init unit test

easy access last element in vector

cleanup naming and implement some destructors

experiment with an emitter abstraction

initial deletion or particles and compression of blocks

test NamedBuffersRef abstraction to separate components

More specifically this separates implementation details of
Forces and ParticleBlocks.

work-in-progress functions to compress a set of particle blocks

initial particles container

initial force implementation

simple Vec3 type

control simulation with some properties

don't reset simulation when pausing playback
