Unable to include ng-walkthrough through use of require

[vshanbha]

We tried to load the ng-walkthrough like any other angular js module using
require('ng-walkthrough')
However it appears that the module does not get loaded and further search (mostly comparing with source of other anuglar modules) suggested that the js file does not export any node style modules.

i.e a statement called module.exports = seems to be missing in the code.

Can we add ability to use require ?
