Dimension prebuilt entity for a LUIS app

[!INCLUDE deprecation notice]

The prebuilt dimension entity detects various types of dimensions, regardless of the LUIS app culture. Because this entity is already trained, you do not need to add example utterances containing dimensions to the application intents. Dimension entity is supported in many cultures.

Types of dimension
