Feature/dynamic template files [draft]

[OskarZaremba]

I found two methods of dynamically modifying files.

• First one - it modifies content of template file by means of template expressions
• Second one - can modify more types of files e.g. typescript files as well and by means of AST (Abstract Syntax Tree)

In my opinion if for the time being we are interested in modifying template files only, our best bet would be to use first method since it is more handy and less labor-intensive.

Let's make more people have a look at it and give their opinions too.

Let's focus on overwriting templates, in this specific case should be easier and faster.
