* If the base name is <code>SimpleName</code> then the suggested name will be <code>SIMPLE_NAME</code>.</li>
* </ul></li>
* <li>{@link #BK_TYPE_NAME}: the base name is a Java simple type name (e.g. <code>HashMap</code>) and all the words of the base name are considered to compute the variable names. A prefix and a suffix can be added to these names.<br>
* There is a heuristic by variable kind.
* <ul>
* <li>{@link #VK_PARAMETER}, {@link #VK_LOCAL}, {@link #VK_INSTANCE_FIELD} and {@link #VK_STATIC_FIELD}:<br>
* In this case a variable name will contain some words of the base name and the first word will be converted to lower case.<br>
* If the type is <code>TypeName</code> then the suggested names will be <code>typeName</code> and <code>name</code>.</li>
* <li>{@link #VK_STATIC_FINAL_FIELD} :<br>
* In this case a variable name will contain some words of the base name, all letters of the name will be converted to upper case and segments will be separated by a underscore (<code>"_"</code>).<br>
