<p>The <code>DiffAlgorithm</code> and <code>MergeAlgorithm</code>
are used to provide the merge capabilities of this project.</p>
<p>Merge is useful when an <code>OfficeDocument</code>
is converted to a "Device" <code>Document</code> format,
and the "Device" <code>Document</code> version is modified.
Those changes can be merged back into the original
<code>OfficeDocument</code> with the merger. The merger is capable
of doing this even if the "Device" format is lossy in
comparison to the <code>OfficeDocument</code> format.</p>
<p>The <code>DiffAlgorithm</code> generates a list of
<code>Difference</code> objects that represent the
differences between two <code>OfficeDocument</code> objects.
It is assumed that one is the original <code>OfficeDocument</code>
object and the other is a "lossy" version of the same
<code>Document</code> with edits to be merged. Typically the
"lossy" version is created by converting a "Device"
<code>Document</code> back into an <code>OfficeDocument</code>.
<p>The <code>MergeAlgorithm</code> takes the <code>Difference</code>
objects as input, and creates a merged <code>OfficeDocument</code>.
A merged <code>OfficeDocument</code> has the following features:</p>
<p><ul>
<li>Tags in the <code>OfficeDocument</code> that are not
supported in the device format are not altered or removed.
<li>Changes made to the device format are merged back into
the <code>OfficeDocument</code> in the location determined by
the <code>DiffAlgorithm</code>.
</ul></p>
<p>Each converter provides an implementation of the
{@link org.openoffice.xmerge.ConverterCapabilities
ConverterCapabilities} which specifies which
<code>OfficeDocument</code> tags are supported for the
device format.</p>
