@Override
	public final BigInteger getBigInteger(Varnode vn, boolean signed) {
		Address addr = vn.getAddress();
		return getBigInteger(addr.getAddressSpace(), addr.getOffset(), vn.getSize(), signed);
	}
A convenience method for reading a value directly from a varnode rather than querying for the
offset and space

@param vn the varnode location to be read
@param signed true if signed value should be returned, false for unsigned value
@return the unsigned value read from the varnode location
