Detailed Description

ColPartition is a partition of a horizontal slice of the page. It starts out as a collection of blobs at a particular y-coord in the grid, but ends up (after merging and uniquing) as an approximate text line. ColPartitions are also used to hold a partitioning of the page into columns, each representing one column. Although a ColPartition applies to a given y-coordinate range, eventually, a ColPartitionSet of ColPartitions emerges, which represents the columns over a wide y-coordinate range.
