	You can use this transaction type to create a task into a particular workboard
	column, or move an existing task between columns.

	The transaction value can be specified in several forms. Some are simpler but
	less powerful, while others are more complex and more powerful.

	The simplest valid value is a single column PHID:

	```lang=json
	"PHID-PCOL-1111"
	```

	This will move the task into that column, or create the task into that column
	if you are creating a new task. If the task is currently on the board, it will
	be moved out of any exclusive columns. If the task is not currently on the
	board, it will be added to the board.

	You can also perform multiple moves at the same time by passing a list of
	PHIDs:

	```lang=json
	["PHID-PCOL-2222", "PHID-PCOL-3333"]
	```

	This is equivalent to performing each move individually.

	The most complex and most powerful form uses a dictionary to provide additional
	information about the move, including an optional specific position within the
	column.

	The target column should be identified as `columnPHID`, and you may select a
	position by passing either `beforePHID` or `afterPHID`, specifying the PHID of
	a task currently in the column that you want to move this task before or after:

	```lang=json
	[
	{
	"columnPHID": "PHID-PCOL-4444",
	"beforePHID": "PHID-TASK-5555"
	}
	]
	```

	Note that this affects only the "natural" position of the task. The task
	position when the board is sorted by some other attribute (like priority)
	depends on that attribute value: change a task's priority to move it on
	priority-sorted boards.
