json5.js and time-elements.js

[ceevee830]

Hello,

I'm trying to compile my polymer app that wants to use sortable-table. I'm getting (correct) errors that json5.js and time-elements.js cannot be found. I grepped through the sortable-table source and found their usage here:

https://github.com/stevenrskelton/sortable-table/blob/master/sortable-table.html
<script src="../json5/lib/json5.js"></script>
<script src="../time-elements/time-elements.js"></script>

I do not see these files in the sortable-table distribution.
Question: what is the best way to get these files compatible with sortable-table?
