Code Improvement
Description:
Changed from passing a structure into a function by value into
passing it in by pointer. Noticed this while compiling with a highly
optimizing compiler which took >30 minutes to analyze the program
(granted, this is the compiler's fault, but in general, it's better
to pass large structures in by pointer and not by value).
Platforms tested:
Linux (specific to h5import, so only needed to test on one platform)
