+/** an interface to map between <i>string</i>s and <i>id</i>s
+
+ <p>a note on atoms:<br>
+ Atoms are abbreviations for strings.
+ When a string gets registered, it is assigned a numeric id
+ so that said string can always be referred to by this id.
+ This way strings have to be transported only once over remote connections.
+ Valid ids are (in this implementation) non zero, signed 32 bit values.
+ An atom of 0 means that the string in question is not registered</p>
+
+ <p>Additionally there is the abstraction of atom class:<br>
+ Atoms are grouped into classes, so that an id can be assigned
+ to multiple strings, depending on the class context. The main
+ advantage of this is that atoms in one class may be kept
+ to small numbers, so that bandwidth can be reduced by sending
+ the atoms only as 16 bit values. Note that it is up to the user in this
+ case to handle overflows.</p>
