(only had to modify generation of groundtruths)
changed initial starting states of robots in dm
added some basic path plotting code to test_simulation

Added a data-generator class to
generate data for simulated_dataset-manager

- internal robot_ctr that resets correctly
Order is (assuming 2 robots):
1: odo, meas
2: odo, meas
1: odo, meas
...

simulation now supports multiple landmarks
added handling for no measurement data
available at a given time (sim not over)

-working on incorporating multiple landmarks
-working on incorporating multiple robots
-working on handling of end of simulation vs. no meas. data available

Added custom noises to simulated_dataset_manager.py
Thorough review of simulated_dataset_manager reveals that it works correctly!
fixed delta_t with regards to alternation between measurement and odometry updates -> scheduling of this will change in next commit
will add multiple robots

Refactored some more elements of the code to be interchangable. Currently debugging communications of request/response messages.

1st iteration, next step is to add dynamic generation.
