cache-size 
A library to quickly get the size and line size of your CPU caches.
Currently this crate only supports x86 CPUs, since it relies on the CPUID instruction, via
the raw_cpuid crate. It is a goal to support other architectures; PRs are
welcome!
Check the Intel 64 and IA-32 Architectures Software Developers Manual
for more information on the CPUID instruction.
