DiskLruCache属于目前最好的Disk Cache库了，但是由于其的存取API，并不是特别好用。
ASimpleCache 提供的API属于比较好用的了。
于是萌生想法，对于其公开的API进行扩展，对外除了原有的存取方式以外，提供类似ASimpleCache那样比较简单的API用于存储，而内部的核心实现，依然是DiskLruCache原本的。
put(String key, Bitmap bitmap)
put(String key, byte[] value)
put(String key, String value)
put(String key, JSONObject jsonObject)
put(String key, JSONArray jsonArray)
put(String key, Serializable value)
put(String key, Drawable value)
editor(String key).newOutputStream(0);//原有的方式String getAsString(String key);
JSONObject getAsJson(String key)
JSONArray getAsJSONArray(String key)
<T> T getAsSerializable(String key)
Bitmap getAsBitmap(String key)
byte[] getAsBytes(String key)
Drawable getAsDrawable(String key)
InputStream get(String key);//原有的用法public class CacheTest extends AndroidTestCase
