This provides classes and interfaces to customise the semantics of `int` channels.

By default, channels are zero-buffered and fully synchronised: both a reader and a writer have to be ready for a communication to proceed. Whoever gets to the communication point first has to wait for the other party.

This package provides a variety of classes conforming to the {@link org.jcsp.util.ints.ChannelDataStoreInt} interface. These classes can be used as plug-ins to the `static` {@link org.jcsp.lang.Channel} manufacturing methods to customise their semantics. Classes are provided for blocking FIFO buffers, overwriting buffers (losing either the newest or oldest data) and infinite (within the realms of your virtual memory) buffers.

Users may write and use their own implementations of the {@link org.jcsp.util.ints.ChannelDataStoreInt} interface, but great care must be taken to specify its semantics. It should not normally be necessary to do this.
