2019-10-24tests: Added GTests for base/str.ccBobby R. Bruce
Adding these tests supercedes the unittest/strnumtest.cc and unittest/tokentest.cc tests. They have thereby been removed. Function "to_number" in base/str.hh previously failed to cast negative float/double numbers. This was due to the use of std::numeric_limits<T>::min() instead of std::numeric_limits<T>::lowest() to determine whether a string-to-float/double conversion was "Out of range". Tests "StrTest.ToNumberFloatNegative" and "StrTest.ToNumberDoubleNegative" exposed this bug. It has been fixed. Methods "split_first" and "split_last" in base/str.hh have had their documentation updated to remove abiguity in their functionality.
