Ajax POST method options added and identation fix

Added new custom options for ajax POST request for extracting data

**New options:**

 - isAjaxPOST : Boolean type, *false* by default
 - dataQuery : The data query or form attribute object to be passed along

**Method:**

```
          if (opts.isAjaxPOST === true) {
              $.ajaxSetup({
                  type: "POST",
                  data: JSON.stringify(opts.query)
                  /* //uncomment if your SSL requires access token
                  , headers: {'X-Access-Token': 'enter_token_here'}, */ 
              });
          } else {
              $.ajaxSetup({
                  type: "GET"
              }); // Loads default GET
          }
```
