MultiSlice
```
public class Slice
extends Object
```
A Slice is used for two purposes
1. To specify a subset of data to extract.
2. To specify a subset of data as specified in a constraint.
In case two, the "last" value of the slice may be undefined (e.q. specifying [0:]) and so they must be filled in at some point. Note that first cannot be undefined because it always defaults to zero; similarly stride defaults to one. Slice Supports iteration. Note that a slice is quite similar to a scalar DataIndex. Modifiied 10/15/2016 to support zero sized slices.

getCount
```
public int getCount()

```
Compare two slices for equality

Overrides:

equals in class Object

Parameters:

o - the other slice to compare with

Returns:

true if this and other are the same, false otherwise

```
Take two slices and compose src wrt target Assume neither argument is null. This code should match ucar.ma2.Section in thredds and dceconstraint.c in the netcdf-c library.
