Subject: [PATCH] Fix: Inline free function operator>> in NumProc.
A non-templated, non-inlined free function may generate
a non-weak symbol which causes linker errors due to
duplicate symbols when the file is used in more than one
compilation unit.
Inlining (which is implicit to non-fully specialized
templated functions) generates weak linker symbols and
hence allows for usage in several compilation units
without linking errors.
