-// Original description: (Schrompf)
-// Adapted to the ASSIMP library because the builtin atof indeed takes AGES to parse a
-// float inside a large string. Before parsing, it does a strlen on the given point.
-// Changes:
-// 22nd October 08 (Aramis_acg): Added temporary cast to double, added strtoul10_64
-// to ensure long numbers are handled correctly
