Compute.java

// Abstract class that takes a Reservoir object as a sort of parent.
// The parent provides a number of resources to Compute object such
// as the weights array and weight index for subclasses to use.
// The subclasses select some part of the reservoir to operate on
// using the reservoir gather method, do a computation and then
// send the result back to some part of the reservoir using 
// the scatter method.  The selected places being decided by
// information in the weights array (or a specific place when
// using scatterWritable.
