Morpho

Currently, Morpho uses the <scope> and <lastId> to generate the next document
id for any new document. When saving locally, if a document with this id already
exists, it will simply be overwritten silently. When saving to the network, the
save will generally fail silently. When there is a naming conflict like this,
the user should be alerted and given options for how to deal with the confict,
such as saving it with a higher revision number, saving it under a different
document id, etc.
