Do a random walk, return the coordinates of each point visited.

* **Parameters:**
  * **chain_len** – Length of the chain to generate.
  * **bead_distance** – Mean distance between consecutive beads (default: 1.0).
  * **mean_squared_bead_distance** – Mean squared distance between consecutive beads (default: 1.0).
  * **seed** – Random seed for reproducibility (default: empty string for random seed).
* **Returns:**
  Coordinates of each point as a flat array (i.e., [x1, y1, z1, x2, y2, z2, …]).
