Error while running example: ERROR: UndefVarError: bounding_rectangle not defined

[andyDoucette]

Issue

The "Simple Example" at https://github.com/JuliaWaveScattering/MultipleScattering.jl doesn't work.

Procedure

Run the "Simple Example":

using MultipleScattering
using Plots

# 2D acoustic medium with density ρ = 1.0 and soundspeed c = 1.0
host_medium = Acoustic(2; ρ=1.0, c=1.0);  

# 2D acoustic particle with density ρ = 10.0 and soundspeed c = 2.0
particle_medium =  Acoustic(2; ρ=10.0, c=2.0); 

p1 = Particle(particle_medium, Sphere([-2.0,2.0], 2.0));
p2 = Particle(particle_medium, Sphere([-2.0,-2.0], 0.5));
particles = [p1,p2];

source = plane_source(host_medium; direction = [1.0,0.0])

simulation = FrequencySimulation(particles, source)

x = [[-10.0,0.0], [0.0,0.0]]
max_ω = 1.0
ω = 0.01:0.01:max_ω
result = run(simulation, x, ω)

time_result = frequency_to_time(result)

# plot(time_result)
plot(simulation,0.8)

gui()

Expected

No error
