At 10, these are the times from three runs:

         atof time = 451
    fast_atof Time = 273
old fast_atof time = 476
The fast method isn't at least three times as fast as atof()

         atof time = 428
    fast_atof Time = 310
old fast_atof time = 531
The fast method isn't at least three times as fast as atof()

         atof time = 406
    fast_atof Time = 309
old fast_atof time = 490
The fast method isn't at least three times as fast as atof()

Averaged:
         atof time = 428.3
    fast_atof Time = 297.3
old fast_atof time = 499

The fast_atof time with the assimp patch and AI_FAST_ATOF_RELAVANT_DECIMALS 10
is approx 1.4x faster than glibc atof. Approx 1.7x faster than stock 1.7.2
fast_atof.

Does assimp have a preferred default? I think we'd need to be higher than 6 to
get it merged, but these numbers look pretty good to me.
