Ring heater thermal equations for cylindrical mirrors

Equations all based on [33] and [34]:

Functions

substrate_deformation_depth(r, z, a, b, c, ...)	Computes the depth displacements throughout the bulk of an optic due to 1W absorption of ring heater.
substrate_temperature(r, z, a, b, c, h, material)	Computes the substrate temperature distribution per Watt absorbed ring heater power.
surface_deformation(r, a, b, c, h, material)	"Computes the surface thermo-elastic deformation of the HR surface per Watt absorbed ring heater power.
thermal_lens(r, a, b, c, h, material[, ...])	Computes the substrate thermal lens per Watt absorbed ring heater power.
zeros_u_m(double a, double h, double tau, ...)	Compute the roots of the equation
zeros_v_m(double a, double h, double tau, ...)	Compute the roots of the equation
