Use do not hardcod names of used classes
Use do not hardcod names of used classes

When a custom parser class inherites from Aba::Parser class, there was
no possibility to use custom parsers for headers, activities or
summaries. In order to use custom parsers, one needed to override
.parse_line method an use custom parsers explicitly.
I did this to allow using custom parsers implemented and storred outside
of this gem.
