Thermal compensation system for the 40m arm cavity

Goal

To compensate for imperfections that arise due to optical inhomogeneities in the arm cavity mirrors by designing and implementing a thermal compensation system. The lessons learned from this exercise will help with designing/implementing a similar kind of system for the folding mirrors in the power recycling cavity.
