<?php

class template
{
   /*
     DESCRIPTION:
     A VERY simple template class. No caching or advanced functionality.
     It simply opens a file and replaces any variable in the file with a syntax of
     '{VARIABLE}' It is primarily designed to keep layout HTML out of php files. Right now it is case sensitive but in future versions i will probably put in a setting for that.
    
I will probably update it with more functionality in the future but for now it could be extended by child classes etc.
