-%% eunit_formatters https://github.com/seancribbs/eunit_formatters
-%% Changes made to the original code:
-%% - Embedded binomial_heap.erl file contents into current file.
-%% - ignore warnings for heap implementation to keep complete implementation.
-%% - removed "namespaced_dicts" dependant preprocessor directive, 
-%%   as it does not apply for our project, we just assume OTP version >= 17.
-%%   This is because the previous verison uses rebar, and we won't do that.
