/**
* This class implements the processing necessary to perform an LDAPv3 add
* operation, which creates a new entry in the directory. An add request
* contains the DN for the entry and the set of attributes to include. It may
* also include a set of controls to send to the server.
*
* The contents of the entry to may be specified as a separate DN and collection
* of attributes, as an {@link Entry} object, or as a list of the lines that
* comprise the LDIF representation of the entry to add as described in
* RFC 2849. For example, the
* following code demonstrates creating an add request from the LDIF
* representation of the entry:
*
* {@code AddRequest} objects are mutable and therefore can be altered and
* re-used for multiple requests. Note, however, that {@code AddRequest}
* objects are not threadsafe and therefore a single {@code AddRequest} object
* instance should not be used to process multiple requests at the same time.
