Including a way to generate a json file like grid.json #320
Description
We've got a bunch of internal docs that support our own work and as we're now using Material Design Icons we want to show them in our docs with the appropriate categories etc. There doesn't seem to be a way to do this within the repo at present.
In the fontIcon folder there is MaterialIcons-Regular.ijmap which just lists the name and codepoint. Ideally I'd to be able to generate something more like https://design.google.com/icons/data/grid.json with the gulpfile included with the repo.
I can see that being useful to many projects which include material icons. Presumably grid.json is maintained in some way like that?
