More advanced Variable Type inferencing

[mvnural]

Cases to consider:

• When unique values < 10 but contain numbers (no string categories)
  • Double values.
  • Integer values. (Does it matter if they are consecutive or not? eg. 1,2,3,4,5 vs. 1, 43, 34,1110 ?)
• When it is inferred as categorical, is there a way to know if it is ordinal or not?
  • May check the header against WolframAlpha API and infer as ordinal if it is a mathematical "unit"

Any other ideas?
