 EOS_Omni's nuc_eos routines use a bisection method to find the temperature
 for a given internal energy. This bisects on the temperature T. I suggest
 to bisect on log T instead, which is a more natural operation.

 For example, if the temperature range is [1...1000] in some units, then
 bisecting in T will examine the sequence 500, 250, 125, ..., and will thus
 perform many table lookups until (say) T=10 is reached. Bisecting in log T
 will find this result much faster.
