Solves the Bloch equations numerically using different integrators.	
Plots the results as well.

Runs and plots Fourier Transform of three components of the electric
field at the posiion of one of the dots from the sim results. Uses 
emission.dats as source file.

Creates a plane of dots parallel in xy-plane.  Some functions commented 
out right now.

Generates a plane using mathematical equation of a plane.  Prints to a
file for sim use and plots plane.

Plots a rings in xy-plane using parametric equations. Writes to file
for sim use.

Plots two rings in xy-plane by checking if points in the plane are
members of the rings, then writing them to a file for sim use.

Plots one ring in xy-plane at any z value by checking if points in the same plane are
members of the rings, then appending them to a file for sim use.  Infinite rings can be
put in one file with this script.

Plots the value of sz for EACH dot in simulation with respect to timesteps.

Grabs the pseudospin data from all dots at any timestep.  this is useful in
checking if the simulation is running as expected at different times.

Generates dots in a specified cube using uniform random distribution algorithm in numpy.
Writes to a file for use in sim.

Finds the two lowest sz values at a specific timestep.  Then finds the corresponding
dots and their positions.  Needs to be generalized still and better organized/commented.
