`pplot(x, w, y, yhat, N, a, t, xreal, xhat, xOld, pdata)`

To be called inside a particle filter, plots either particle density (`density=true`) or individual particles (`density=false`) 

Will plot all the real states in `xIndices` as well as the expected vs real measurements of `yIndices`.

Arguments:

* `x`: `Array(M,N)`. The states for each particle where `M` number of states, `N` number of Particles

* `w`: `Array(N)`. weight of each particle

* `y`: `Array(R,T)`. All true outputs. `R` is number of outputs, `T` is total number of time steps (will only use index `t`)

* `yhat`: `Array(R,N)` The expected output per particle. `R` is number of outputs, `N` number of Particles

* `N`, Number of particles

* `a`, `Array(N)`, reordering of particles (e.g. `1:N`)

* `t`, Current time step

* `xreal`: `Array(M,T)`. All true states. `R` is number of states, `T` is total number of time steps (will only use index `t`)

* `xhat`: Not used

* `xOld`: Same as `x`, but for previous time step, only used when `!density` to show states origins

* `pdata`: Persistant data for plotting. Set to void in first call and pdataOut on remaining 

* `density = true` To only plot the particle trajectories, set (`leftOnly=false`)

* `leftOnly = false`\n

* `xIndices = 1:size(x,1)`

* `yIndices = 1:size(y,1)`

Returns: `pdataOut`
