Started writing JSON Schema... not sure if doing right.

app/js/common/JSONSchema.js

+
+
+var NESPaletteSchema = JSON.stringify({
+  "$schema": "http://json-schema.org/draft-07/schema#",
+  "$id": "NESPaletteSchema.json",
+  "type":"array",
+  "minItems":25,
+  "maxItems":25,
+  "items":{
+    "type":"number",
+    "minimum": 0,
+    "exclusiveMaximum": 64
+  }
+});
+
+
+var PalettesStoreSchema = JSON.stringify({
+  "$schema": "http://json-schema.org/draft-07/schema#",
+  "$id": "PalettesStoreSchema.json",
+});
