CMStateSet (Smooks 2.0.0-RC4 API)

java.lang.Object
- org.smooks.engine.delivery.sax.ng.org.apache.xerces.impl.dtd.models.CMStateSet

```
public class CMStateSet
extends Object
```
This class is a very simple bitset class. The DFA content model code needs to support a bit set, but the java BitSet class is way, way overkill. Our bitset never needs to be expanded after creation, hash itself, etc... Since the vast majority of content models will never require more than 64 bits, and since allocation of anything in Java is expensive, this class provides a hybrid implementation that uses two ints for instances that use 64 bits or fewer. It has a byte array reference member which will only be used if more than 64 bits are required. Note that the code that uses this class will never perform operations on sets of different sizes, so that check does not have to be made here.
