To be done
- Use constraints for types? E.g., allow for float or empty
 anchor(:DataSource, ?Type) is nondet
True when the top-level of DataSource is an anchor of Type. This implies it is a cell the given Type and the cells left and above it are of different types.

The anchor/2 predicate is used to generate candidates for creating larger units of cells. For example, to generate all blocks of floats, use this:

?- anchor(D, float), once(block(D, float)).
 unassigned_anchor(:DataSource, ?Type) is nondet
 block(:DataSource, ?Type) is nondet
 block(?Sheet, ?SX, ?SY, ?EX, ?EY, ?Type) is nondet
A block is the largest rectangular area of cells of the same Type that starts at SX,SY. A block consists minimally of two cells, stacked either horizontally or vertically.
 cell_class(:Sheet, ?X, ?Y, ?Class) is nondet
Classification of cells. Defined classes are:
  • string
  • float
  • percentage
  • empty
  • style(Style)
 sheet_bb(:Sheet, ?DS) is nondet
True if DS is a datasource that describes all cells in Sheet. Fails of the sheet is empty.
