Subject: thermo optic noise added to noise budget 

Thermo optic noise (coating) calculation has been added to the noise budget code.

      The previous result (for example, see psl:901) was not done properly. What I did was calculated the TO noise using GWINC code independently then plotted the result on top of the noise budget. Now the calculation is included in the main noise budget file (by calling function from GWINC). The noise budget for shorter cavity can be done easily by changing the length of the cavity only. For 1.45" long cavity, the TO noise in coating will not be the dominant noise source.
