create "odmRef"

[mjkoster]

We resolved to create another ODM reserved word, odmRef

• odmRef is similar to $ref in that it takes a pointer to a definition as a value
• odmRef carries the "semantic breadcrumbs"

e.g.

{
  "odmProperty" : {
    "rChannel": { "odmRef": "#/odmData/colorChannelData" },
    "gChannel": { "odmRef": "#/odmData/colorChannelData" },
    "bChannel": { "odmRef": "#/odmData/colorChannelData" }
  },
  "odmData": {
    "colorChannelData": {
      "type": "number",
      "minumum": 0,
      "maximum": 256
    }
  }
}

We should be able to remove "odmType" because odmRef can be defined to carry the semantic breadcrumb from its references definition

when odmRef is used, the qualities of the referenced definition are included in the current declaration Additional qualities may be defined to customize the current declaration beyond the referenced definition
