Calculates the position of a receiver given the time delay of arrival to at least 4 satellites in 3D (or at least 3 satellites in 2D).
INPUTS:
  1. satPos is Cartesian location of satellites (in 1D, 2D, or 3D). Each row is the position of one satellite.
  2. tVals is the arrival time of the signal = distance from
  3. satellite to reciever + offset b
OUTPUTS:
  1. eX estimated position of the user
  2. eb estimate of the offset time b

1.0.3

Corrected some grammar and inconsistency in the comments. Also added debugging code when the code is run in default form.
1.0.2

Added plotting in 3D (and in 1D). the original only plotted in 2D. Also added some logic because in 1D one can only determine the correct position if the user is within the span of the satellites.
1.0.1

Added plotting in 3D and 1D (original version only plotted in 2D)
