Description 

Author

This class provides a trait to process templates with class functions.

It can be included on a class to process templates and use the class function call return values or variable values to replace in the template.

The template engine can compile the templates into PHP scripts and cache them to avoid further processing. It also supports:

1. Conditional sections
2. Foreach iteration loop sections
3. Include external templates

Template engines are frequently used in PHP applications to generate Web pages or some kind of other output from template files or strings, as they make it easy to separate login from presentation code.

Usually you use a component that processes a template file or a string and replaces some variables with values passed to the template engine.

This package provides an alternative approach by using a trait that can be used by any class. The template variables are replaced by the values of class variables or return values of class functions with the same names.

This way developers can easily turn templates into classes of their own that they can call to generate their applications output.
