Detailed Description

XBar bytes can be shared by multiple tables for different purposes. These cases can happen:

• One table can use the same data for two purposes
• Two tables can use the same data for whatever purposes
• Each table use different slice of the byte for different purposes, slices do not overlap
  • (validity bits)
• Mutually exclusive tables source mutually exclusive data from the same byte
• Use might be duplicated (bug possibly?) This is why this structure is held inside set and implements < operator so we can deduplicate these cases.
