ConfigParser.getStrict

Alternative form strict config value getter, returning the retrieved value via a reference. (The advantage being that the template type can then be inferred by the compiler.)

Template can be instantiated with integer, float or string (istring) type.

Usage Example:

Config.parseFile("some-config.ini");
// throws if not found
istring str;
int n;

Config.getStrict(str, "some-cat", "some-key");
Config.getStrict(n, "some-cat", "some-key");
