Missing unit conversion in noise expression of Brumley's chemotaxis #16

Maybe this line should become

σ = Π * 0.04075 * sqrt(3*u / (π*a*Dc*Δt^3)) # noise

where 0.04075 is a correction factor arising from proper unit conversions (calculations explained in enclosed pdf) Noise in the Brumley-Carrara model of chemotaxis.pdf

Such a correction affects the resulting behavior crucially.
