Detailed Description

AbstractPkg takes care how to generate code from template/PKG
package area. The PKG can be any directory which may include
any types of files, e.g. C++ (.cc), python (.py), etc.
This class relies on specific logic which we outline here:

    - each template may use tags defined with double underscores
      enclosure, e.g. __class__, __record__, etc.
    - each template may have example tags, such tags should
      start with @example_. While processing template user may
      choose to strip them off or keep the code behind those tags
    - in addition user may specify pure python code which can
      operate with user defined tags. This code snipped should
      be enclosed with #python_begin and #python_end lines
      which declares start and end of python block
