CPU
===
Simple Example
---------------
To get CPU count::
>>> from plyer import cpu
>>> # 1 socket, 1 core per socket, 2 threads per core
>>> cpu.sockets # 1 CPU socket (or slot)
1
>>> cpu.physical # 1 CPU socket * 1 core per socket
1
>>> cpu.logical # 1 CPU socket * 1 core per socket * 2 threads per core
2
Supported Platforms
-------------------
MacOS
Linux
Windows
