Render a Macro in a Template

[frost-byte]

Add renderTemplateMacro to Twig wrapper Update README

I needed to update a view using an ajax call; this allows you to just run a macro from a template.

In my understanding, macro is a function used in templates. So I don't want to merge this PR.

How about extending Twig library for your use case?

[frost-byte]

That's fine, I'm looking in how to use my fork via composer. I suppose that means that I'll need to watch your repo and merge in any releases you make.

1. Create your Twig library which extends Twig class in this repository.
2. Use your own Twig library.

For example: 1.

require_once __DIR__.'/Twig.php';

class My_twig extends Twig
{
    public function renderTemplateMacro($view, $macro, $params = [])
    {
        ...
    }
}

2.

$this->load->library('my_twig');

Thanks, that works.
Though, I can't access the private properties of the Twig class. I guess I'm just supposed to call getTwig in any class that extends yours? (Otherwise you'd have to make them protected properties.)

[kenjis]

@frost-byte I guess so. Why do you want to access the private properties?

[frost-byte]

That was meant as an aside. It's not necessary. But, it seemed strange for an extended class to call a getter of its parent. (I needed access to the twig property)
