Allows you to include dynamically a single file, a list of files or a whole directory. No more tedious include statements.
Background
This is designed to be similar to Java's package system but instead uses a directory, file/s or */ALL, and include type(INC, IN_O, REQ, REQ_O). The reason is it can become a hassle if you want to include a bunch of files or templates for smarty or phar files in your code. Now its possible to include all of these with 4 lines of code.
The Code
Dynamic include of phar,tpl, and php files in your projects. uses a predefined class which implements an interface for those who'd like to create their own version.
Import class name: class_import.php
Sample Resources
Include files: Make sure that they are all in the same directory of the sample will not work. It expects them to all be in the same folder.
