support for generating test cases based on multiple template template
types combined with template arguments for each of the template template
types specified
e.g.
```
TEMPLATE_PRODUCT_TEST_CASE("template product","[template]",
(std::tuple, std::pair, std::map),
((int,float),(char,double),(int,char)))
```
will effectively create 9 test cases with types:
std::tuple<int,float>
std::tuple<char,double>
std::tuple<int,char>
std::pair<int,float>
std::pair<char, double>
std::pair<int,char>
std::map<int,float>
std::map<char,double>
std::map<int,char>
Tested type is accessible in test case body as TestType
Unique name is created by appending ` - <index>` to test name
since preprocessor has some limitations in recursions
