I created a simple string template formatter (no if-then-else, no include, 
just substitution of variables).

Example:

"First phrase: {1}. Second phrase: {2}."

This formatter is suitable for short strings, such as phrases for gettext.

My code was not tested!

Dmitry, I ask you to add something like this to your Simple Components.

My program anyway uses Simple Components, so after you implement it, I can 
remove these files from my sources.

I released the files in question both GPLv3 and Apache License 2.0. So feel 
free to use it as a coding example.
