* Converts a byte-count to a formatted string suitable for display to the user, with respect

* For instance:
|
|
* <ul>
|
|
* <li><code>format(918)</code> returns <em>"918 B"</em>.</li>
|
|
* <li><code>format(98765)</code> returns <em>"96 KB"</em>.</li>
|

* <li><code>format(1238476)</code> returns <em>"1.2 MB"</em>.</li>

|
* This class assumes that 1 KB is 1024 bytes.
