Template JS Engine: Template engine that takes objects as parameters

This object implements a template engine that takes objects as parameters.

It takes a given template string and an array of objects with parameter values that will be used to replace marks in the template string delimited by curly braces { } .

Marks that appear in the template string consecutively indicate that they should be replaced by values of sub-objects of the parameter value objects.

The resulting processed template is inserted in given HTML page elements.

The object may also just return an array of template keys with the respective replacement values.
