tomlplusplus/tests/manipulating_values.cpp
Mark Gillard f6450f6ff9 moved is_homogenous to toml::node 
also:
- added is_homogenous overload for identifying failure-causing element (to assist with implementing #45)
- added table::is_homogenous
- added value::is_homogenous (just for generic code's sake)
