Make schemas shareable

[jeromatron]

It would be nice to be able to share schemas with others, including perhaps the distributions in the second tab. The schema itself would be fine as a start though.

If you export the cassandra-stress.yaml you essentially have all the information about the schema and the field distributions. Does that satisfy this requirement? @jeromatron ?

[jeromatron]

Yes for sharing I think that's fine. Also would there be value in being able to import them into the tool as well to tweak things with the interface?

Yeah let's re-focus this issue to address import export. I'll have to add a js yaml parser but it could work nicely.
