“ The time so spent by the expert is a substitute for lawyer time, just as paralegal time is, for if prohibited (or deterred by the cost) from hiring an expert the lawyer would attempt to educate himself about the expert's area of expertise. To forbid the shifting of the expert's fee would encourage underspecialization and inefficient trial preparation, just as to forbid shifting the cost of paralegals would encourage lawyers to do paralegals' work. ”
