error in README.md

under the Filtering section:

``` c
char** jsonFilter = {"name,"format","height","width",NULL};
 aJsonObject* jsonObject = aJson.parse(json_string,jsonFilter);
```

it lost a "...

it should be:

``` c
char** jsonFilter = {"name","format","height","width",NULL};
 aJsonObject* jsonObject = aJson.parse(json_string,jsonFilter);
```
