ik扩展支持Solr配置

扩展ik原生代码：
public class IKAnalyzerTokenizerFactory extends TokenizerFactory
{
private boolean useSmart;

public boolean useSmart()
{
return this.useSmart;
}

public void setUseSmart(boolean useSmart) {
this.useSmart = useSmart;
}

public IKAnalyzerTokenizerFactory(Map args) {
super(args);
assureMatchVersion();
setUseSmart(((String)args.get("useSmart")).toString().equals("true"));
}

public Tokenizer create(AttributeSource.AttributeFactory factory, Reader input)
{
Tokenizer _IKTokenizer = new IKTokenizer(input, this.useSmart);
return _IKTokenizer;
}
}

将ik重新打包，solr中配置信息如下：
