Added Test Script & Debug Report to Documentation
Slight logic/variable scope modifications in:
DagaGenerator and SimulatedDatasetManager

avoids cropping off time at the end of sim

data_generator and Simlated Dataset Manager -
    Updated to allow for user inputted velocity

    Deleted redundant code in request part of SDM
    (code extraneously copied value to msg sent out)

   In find_measurent(), updated to differentiate
   landmark over relative observations ( & prefer)

   Need to figure out what's wrong with velocity
   Then, need to test communication

time index even when no measurement available at a particular time

Replaced hard-coded assumption with
find_nearest_time_idx()

Updated journal 2 sim parameters
Still debugging!

realtime plot merge

Currently testing communication

added relative observations
added testing for relative observations

TODO - multiple robots (modify datastructures), math
stays the same
Tested on both simulated and real-world data, works in both cases

Small tweaks in parameter passing in simulated dm

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