Major Description
Validate.inclusiveBetween() is often going to be used with primitives, so it might make sense to add
inclusiveBetween(long start, long end, long value)
and
inclusiveBetween(long start, long end, long value, String message)
This would avoid the overhead of using boxing and compareTo() for the primitive number types.
Note: I tried adding
inclusiveBetween(long start, long end, long value, String message, Object ... values)
but that causes the compiler to complain about ambiguous methods.
However, that's unlikely to be needed much.
