/**
* Testing <code>com.sun.star.container.XNameContainer</code>
* interface methods :
* <ul>
*  <li><code> insertByName()</code></li>
*  <li><code> removeByName()</code></li>
* </ul>
* This test needs the following object relations :
* <ul>
*  <li> <code>'INSTANCE1', ..., 'INSTANCEN'</code> : N relations
*   which represents objects to be inserted. See below
*   for more information.</li>
*  <li> <code>'XNameContainerINDEX'</code> : For internal test
*   usage. Contains current thread number. </li>
*  <li> <code>'XNameContainer.AllowDuplicateNames'</code> <b>optional</b>:
*   if this relation exists then container elements can have duplicate
*   names. </li>
*  <li> Test environment variable <code>'THRCNT'</code> : number
*   of interface threads running concurrently. </li>
* <ul> <p>
* XNameContainer needs n ObjectRelations "INSTANCEn" , where n=1, ..., THRCNT.
*
* When this interface tested by different threads, it must use different
* instances to insert/remove - one for each thread.
*
* That's why we use objRelation "XNameContainerINDEX" to store the number of
* last taken instance. If there is no such relation, it initialize with 1.
*
* If you insert the same Object by insertByName() several times you
* don't insert the Object several times. The first insertByName() inserts
* the Object to the Container but all other insertByName() changes
* the Name in the Container because it's the same Object.
* @see com.sun.star.container.XNameContainer
