cast error in symbolic package

[Stephen Siegel]

Run any of the tests and cast exception is thrown:

java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double

Offending code seems to be here in SymConcreteValue.java:

	public SymConcreteValue(SymType type, Object value)
	{
		super(type);
		this.concreteValue = value;
		if(!((SymSimpleType)type instanceof SymBoolean))
		{
			if((SymSimpleType)type instanceof SymInteger)
			{
				if(((Integer)value).intValue() == 0)
				{
					isZero = true;
					isOne = false;
				}
				else if(((Integer)value).intValue() == 1)
				{
					isOne = true;
					isZero = false;
				}
				else
				{
					isZero = false;
					isOne = false;
				}
			}
			else
			{
				if(((Double)value).doubleValue() == 0.0)
				{
					isZero = true;
					isOne = false;
				}

Bug fixed. I removed the primitive types from the type table but I still tried to get them from the type table in some methods in symbolic universe.
