Rename Template into TemplateProcessor

[ghost]

Suggest renaming Template class into TemplateProcessor, because latter matches its purpose the best.

Template is not an instance of the Template class, it's a file on hard drive. The class loads template's content and processes it. Please, take a look at the definition also.

TemplateProcessor class could evolve into a separate component in the future, but, for now, I suggest just renaming.

I basically agree that TemplateProcessor is better than Template for this class name. I have two other alternatives:

1. Place the Processor class under Template subnamespace, i.e. Template\Processor
2. Place the TemplateProcessor under Utility (or other better name) subnamespace. This new subnamespace will hold other utilities such as style importer, format converter, etc.

Creating directory just for one class is not a good idea, on my mind, at all. :)

I'm not 100% sure but doe this use the Mail Merge functionality? If so it might make sense to use MailMerge as the namespace. Perhaps MailMerge\DocumentProcessor?

The process worked like mail merge, but we don't use mail merge component. Which reminded me that we don't have mail merge component, yet.
