◆ isAngleBracketString()

This function checks if the next token is type or arithmetic.

string that begin with character '<' must end with character '>'. otherwise it is arithmetics. If the function returns a 'true' value, the End argument will be filled with the last location pointed to the '>' character. There is a gap between the AltMacro's documentation and the single quote implementation. GCC does not fully support this feature and so we will not support it. TODO: Adding single quote as a string.
