/**
* Cogent - a content generation "agent"
* An abstract class for generating HTML content by scanning a directory
* containing sub-directories with presentable content. The simple goal
* is to make it quick to throw together code that generates HTML by scanning
* the filesystem in cases where a bunch of content is organized over a flat
* directory structure with meaningful folder names.
*
* Cogent provides generic methods for listing directories under a root
* path, and files matching a filter. The indended use for this class is
* for children to define a public method called "generate" which does the
* actual work of writing HTML based on what it found during the directory scan.
*
* Outline:
* Cogent("<directory name>", <array of filename suffixes>)
* Cogent->scan(); // scans all directories under <directory name> for content matching provided filters (conjunctive)
* Cogent->generate(); // generates HTML output for all images found, organized by album
*
