WiP: feature TemplateBuilder

[pvojtechovsky]

A new way how to create a template from any type or any part of type. See example in #1458.

Features:

• any type can be used as source of the template
• the part of the source type can be excluded/ included in template by excludeXxx and includeXxx methods. It allows to define one Template type and use it for more related template substitutions. For example 1) create the build type, 2) add all builder methods. Both steps based on same template type, but using different type members.
• the new type can be created from template
• the template can be applied to existing type
• substitution parameters are wrapped into substituteXxx methods, which allows more user friendly definition of template parameters.

This code is experimental I will play with it first and I expect it will be finished in 1 month.
