yaep.tst.in does not exist

[brandonneth]

The Readme says to see the yaep.tst.in file, which does not seem to be part of the repository

Thank you for reporting this. Earlier all tests were in one huge shell file yaep.tst.in. People did not like it. So it was replaced by separate tests in directories C/test or C++/test.

I've just fix README.md file (removed mentioning the file).
