/***********************************************************************************************************************
 *
 * &lt;p&gt;A default implementation of the {@link BlogViewController} that is independent of the presentation technology.
 * This class is capable to render:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;blog posts (in various ways)&lt;/li&gt;
 * &lt;li&gt;an index of the blog&lt;/li&gt;
 * &lt;li&gt;a tag cloud&lt;/li&gt;
 * &lt;/ul&gt;
 *
 * &lt;p&gt;It accepts path parameters as follows:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;{@code &lt;uri&gt;}: selects a single post with the given uri;&lt;/li&gt;
 * &lt;li&gt;{@code &lt;category&gt;}: selects posts with the given category;&lt;/li&gt;
 * &lt;li&gt;{@code tags/&lt;tag&gt;}: selects posts with the given tag;&lt;/li&gt;
 * &lt;li&gt;{@code index}: renders a post index, with links to single posts;&lt;/li&gt;
 * &lt;li&gt;{@code index/&lt;category&gt;}: renders an index of posts with the given category;&lt;/li&gt;
 * &lt;li&gt;{@code index/tag/&lt;tag&gt;}: renders an index of posts with the given tag.&lt;/li&gt;
 * &lt;/ul&gt;
 *
 * &lt;p&gt;Supported properties of the {@link SiteNode}:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;{@code P_CONTENT_PATHS}: one or more {@code Content} that contains the posts to render; they are folders and can have
 *     sub-folders, which will be searched for in a recursive fashion;&lt;/li&gt;
 * &lt;li&gt;{@code P_MAX_FULL_ITEMS}: the max. number of posts to be rendered in full;&lt;/li&gt;
 * &lt;li&gt;{@code P_MAX_LEADIN_ITEMS}: the max. number of posts to be rendered with lead-in text;&lt;/li&gt;
 * &lt;li&gt;{@code P_MAX_ITEMS}: the max. number of posts to be rendered as links;&lt;/li&gt;
 * &lt;li&gt;{@code P_DATE_FORMAT}: the pattern for formatting date and times;&lt;/li&gt;
 * &lt;li&gt;{@code P_TIME_ZONE}: the time zone for rendering dates (defaults to CET);&lt;/li&gt;
 * &lt;li&gt;{@code P_INDEX}: if {@code true}, forces an index rendering (useful e.g. when used in sidebars);&lt;/li&gt;
 * &lt;li&gt;{@code P_TAG_CLOUD}: if {@code true}, forces a tag cloud rendering (useful e.g. when used in sidebars).&lt;/li&gt;
 * &lt;/ul&gt;
 *
 * &lt;p&gt;The {@code P_DATE_FORMAT} property accepts any valid pattern in Java 8, plus the values {@code S-}, {@code M-},
 * {@code L-}, {@code F-}, which stand for small/medium/large and full patterns for a given locale.&lt;/p&gt;
 *
 * &lt;p&gt;Supported properties of the {@link Content}:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;{@code P_TITLE}: the title;&lt;/li&gt;
 * &lt;li&gt;{@code P_FULL_TEXT}: the full text;&lt;/li&gt;
 * &lt;li&gt;{@code P_LEADIN_TEXT}: the lead-in text;&lt;/li&gt;
 * &lt;li&gt;{@code P_ID}: the unique id;&lt;/li&gt;
 * &lt;li&gt;{@code P_IMAGE_ID}: the id of an image representative of the post;&lt;/li&gt;
 * &lt;li&gt;{@code P_PUBLISHING_DATE}: the publishing date;&lt;/li&gt;
 * &lt;li&gt;{@code P_CREATION_DATE}: the creation date;&lt;/li&gt;
 * &lt;li&gt;{@code P_TAGS}: the tags;&lt;/li&gt;
 * &lt;li&gt;{@code P_CATEGORY}: the category.&lt;/li&gt;
 * &lt;/ul&gt;
 *
 * &lt;p&gt;When preparing for rendering, the following dynamic properties will be set, only if a single post is rendered:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;{@code PD_URL}: the canonical URL of the post;&lt;/li&gt;
 * &lt;li&gt;{@code PD_ID}: the unique id of the post;&lt;/li&gt;
 * &lt;li&gt;{@code PD_IMAGE_ID}: the id of the representative image.&lt;/li&gt;
 * &lt;/ul&gt;
 *
 * &lt;p&gt;Concrete implementations must provide two methods for rendering the blog posts and the tag cloud:&lt;/p&gt;
 *
 * &lt;ul&gt;
 * &lt;li&gt;{@link #renderPosts(java.util.List, java.util.List, java.util.List) }&lt;/li&gt;
 * &lt;li&gt;{@link #renderTagCloud(java.util.Collection)  }&lt;/li&gt;
 * &lt;/ul&gt;
