return value type fix & change default value type

[jialeicui]

In function ' intervalStart ' & ' intervalStop ', the return value type may be typename K
and change the default value type to std::size_t, so I can use larger value by default

I'm writing a small program: load some ip ranges cover IPv4, input an ip address and return the range index.
So I thought std::size_t work well with common integer data types.
I changed the default value type, it's an easy way to change the default value type by defining inter_type

In the interest of minimizing the namespace of the library, let's just use
size_t here. There are only two places it's used. Would you please update
the patch? Sorry for the trouble.
