Data tree
<!-- ##### SECTION Long_Description ##### -->
<para>
An #EphyNodeDb is a database for arbitrary data organized in a tree.
</para>
<para>
Each database is stored along with its name in a global set of databases.
Databases can be created using ephy_node_db_new() and retrieved using
ephy_node_db_get_by_name().
</para>
<para>
Each #EphyNode inside an #EphyNodeDb is identified by a unique node ID. By
keeping a handle on the ID, one can use ephy_node_db_get_node_from_id() to
retrieve its corresponding #EphyNode.
</para>
<para>
#EphyNodeDb<!-- -->s can be saved to disk using ephy_node_db_write_to_xml_safe()
and restored using ephy_node_db_load_from_file().
