numeric conversion for matlab
Voyager.yaml now works in both matlab and python. But to make it work in matlab, I had to format some of the values as explicit floats by adding '.0' to the end. (Specifically, when using Voyager matgwinc, the suspension noise calculation threw errors when the per-stage temperature values were not formatted as explicit floats.)
When shipping an IFO structure over to matlab, should we have it represent ints as floats by default, the way matlab typically does?
