Scale wide twin data
Scale wide data across all twins. You offer up a list of variables to scale, e.g. c("DEP", "bmi")
and the separator (e.g. sep = "_T") and twin suffixes e.g. 1:2 that paste together to make
complete variable names: e.g. "DEP_T1" and "DEP_T2".
umx_scale_wide_twin_data(varsToScale, sep, data, twins = 1:2)
