[RM-7475] [refactor] derive CLineCatalog from TLineVector

Created on 2022-09-01 15:14:57 by Didier Vibert. % Done: 0

CLineCatalog is essentially a container for one member :

<pre><code class="cpp">
TLineVector m_list;
</code></pre>

it would be better to try to redeclare it as a derived class of TLineVector which is an STL vector (std::vector<CLine>)

it then enables to pass the full CLineCatalog instance where we pass only a TLineVector, and will avoid code duplication to manipulate the TLineVector....
