* Entire File: MY new IDE installation did not have tabs=4 spaces set. I changed this, & due to the way Git works it cause massive changes as tab content has changed to space content.
* Entity Class: Was currently too dependent on the RESTUtil class - called static RESTUtil methods inside of its methods, which basically meant that the Entity class could not function without the RESTUtil class. Refactored to make Entity Class more independent, which will a) help with portability, and b) is the Right Thing To Do
* Entity Class : Completed listAll() to list multiple data items. views() was modified to call listAll()
* RESTUtil Class : modified process()'s 'get' clause to work for both Entity->view() and Entity->listAll() methods
* Class Entity : add() now returns the record ID created for the last query,
* Class RESTUtil : process() updated to send the newID in a response message,
** Class Database : added new method newID() to return the record ID created for the last query
Moved classes out of api.php and into their own files in the class directory. Also class file names now start with 'class_'
