# Thanks for all the help SimpleCov https://github.com/colszowka/simplecov-html
# initial version pulled into Coverband from Simplecov 12/04/2018

# Classifies whether lines are relevant for code coverage analysis.
# Comments & whitespace lines, and :nocov: token blocks, are considered not relevant.
