[lmi-commits] [lmi] master 0d512f5 6/9: Add a never-before-implemented variable

[Greg Chicares]

branch: master
commit 0d512f51347d4aa4e9ec8adcab4805e7195ecece
Author: Gregory W. Chicares <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Add a never-before-implemented variable
    
    "Policy year", by convention, begins at one. It's useful to provide
    "Duration" (which was already in the format map) as an alternative
    for those who think in origin zero.
