# small library which can generate tap comaptible files
# If you want to stream as you run, you will need to fale header total infomration
# start your output or each sub suite with `tapHeader total meta1 meta2 .. metaN` call. only totla is mandatory
# print individual tests with `tapTestStart ok/not ok, numerical id and title` (three) params
# print details by `tapLine id content`
# or by `tapFromFile id alias`  where each file is head/grep/tail or message that it do nto exists is printed (alilas is wildchar or human readabel explanation of file)
# close each test by `tapTestEnd`



## First mandatroy argument is number of tests
## all others are strings, written in as header metadata
