[lmi-commits] [lmi] master e388f6e 037/156: Add beginning of numeric summary page using an external template

[Greg Chicares]

branch: master
commit e388f6e52fa3df2a2e1d0fa83ca2346c4806ebf7
Author: Vadim Zeitlin <address@hidden>
Commit: Vadim Zeitlin <address@hidden>

    Add beginning of numeric summary page using an external template
    
    Switch to using external templates instead of generating page contents
    from C++ code.
    
    This requires defining some extra artificial variables, as external
    templates can't contain any logic, but significantly increases
    flexibility.
