[lmi-commits] [lmi] master 957ead4 2/3: Improve physical design

[Greg Chicares]

branch: master
commit 957ead4651ce312a744f36eb4742194fda20d786
Author: Gregory W. Chicares <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Improve physical design
    
    Moved implementation of operator<<() out of line so that class header
    doesn't need to include <ostream>. See:
