Loader (EasyTest to ease Data Driven Testing 1.3.2-SNAPSHOT API)

All Known Implementing Classes:

CSVDataLoader, EmptyLoader, ExcelDataLoader, XMLDataLoader
```
public interface Loader
```
An interface for different types of loader. This would ultimately be used by the users of EasyTest as well to provide their custom Loaders. Currently, EasyTest supports three Loaders internally :
ExcelDataLoader - To load data from XLS files
XMLDataLoader - To load data from XML files. Look at the Schema for XML at : https://github.com/EaseTech/easytest-core/blob/master/src/main/resources/testDataSchema.xsd
CSVDataLoader - To load data from a CSV file In addition users can define their own custom Loaders and use them in their test classes by specifying the LoaderType.CUSTOM loader type in their DataLoader annotation

```
Map<String,List<Map<String,Object>>> loadData(Resource resource)
```
    Method responsible to Load the test data from the Resource instance passed as parameter
    
    Parameters:
    resource - from which to load the data
    
    Returns:
    a Map consisting of the methodName as key and a List of Key/value pairs as the value of the Map. This is currently not a user friendly way of exposing the test data.

```
    Method responsible for writing the test data and actual result back to the file
    
    Parameters:
    resource - the resource to which data needs to be written
    methodNames - the names of the method to write the data for
    actualData - a Map consisting of the methodName as key and a List of Key/value pairs as the value of the Map. This Map contains the input as well as output data This is currently not a user friendly way of exposing the test data.
