Change version number in the manifest file

Node and nom specifically require version numbers to comply with node-semver semantic versioning structure.  "1.0" is an invalid version number and causes npm to fail, even when trying to work with other installed node modules.

I changed the version number to 0.1.0 both to make it semantically valid but also to reflect the fact that the API is incomplete and subject to change.
