proposed DI water structure

[turbomam]

I don't feel confident about how far out this should be axiomitized, or whether deionization should be thought of as a purification or as a material component separation

I haven't attempted to find a safe range of OBI ids yet.

• use your ID range
• Should be a subclass of ENVO:water
• Add definitions
• There is an argument for putting in ENVO but as this is primarily a material created artificially OBI is fine

OBI doesn't have user ID ranges. Please use this Google Sheet to get an ID: https://docs.google.com/spreadsheets/d/1tpDrSiO1DlEqkvZjrDSJrMm7OvH9GletljaR-SDeMTI/edit#gid=224833299

We define ENVO imports in this file: https://github.com/obi-ontology/obi/blob/master/src/ontology/OntoFox_inputs/ENVO_input.txt
