Reading content of file into String in scala

One of the common requirements is to read content of a file into String, You would want to read content of config file at particular path in your program at runtime but during testing you would wan to read content of a file on class path. I built this simple class that takes has following 2 methods

1. getFilePathContent(): This method takes full path of file and reads its content into string
2. getResourceContent(): THis method takes relative path of a file already available on classpath and converts it into String
