```
A cell in a spreadsheet.
The cell has content, which can be interpreted in different ways:
- As a formula - The content should consitute a syntactically correct expression, and begin with an assignment.
- As a value - If the cell contains a formula, the formula is evaluated to produce a value, provided that the cell does not contain calculation errors (e.g. division by 0). Otherwise, the content is interpreted as the value.

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`addCellListener(CellListener listener)` Registers the given listener on the cell.
`void`	`clear()` Clears the content of the cell.
`void`	`copyFrom(Cell source)` Copies all data from the source cell to this one.
`Address`	`getAddress()` Returns the address of the cell.
`CellListener[]`	`getCellListeners()` Returns the listeners that have been registered on the cell.
`String`	`getContent()` Returns the content of the cell, as entered by the user.
`SortedSet<Cell>`	`getDependents()` Returns the dependents of the cell, i.e. the cells that contain a reference to the cell in their formula.
`Formula`	`getFormula()` Returns an expression representing the cell's formula.
`SortedSet<Cell>`	`getPrecedents()` Returns the precedents of the cell, i.e. the cells that the formula in the cell references.
`Spreadsheet`	`getSpreadsheet()` Returns the spreadsheet to which the cell belongs.
`Value`	`getValue()` Returns the value of the cell.
`void`	`moveFrom(Cell source)` Moves all data from the source cell to this one.
`void`	`removeCellListener(CellListener listener)` Removes the given listener from the cell.
`void`	`setContent(String content)` Sets the content of the cell and if it starts with the assignment operator attempts to parse a formula from it.
