Creating a client app for RAD Server

Let’s now create a client application for the REST API we just built with RAD Server. We’ll do this by reusing the UI and some of the code from the previous versions:

Create a new, blank multi-device project and save it as ToDoListEMS in the client folder.
Keep the default name of the main form. It does not matter because in a moment we are going to remove it from the project.
Add to the project the uToDoTypes and uToDoUtils units.
Add a new data module to the client project. Save it as uDMToDoEMS and change its Name property to DMToDoEMS.
Add uToDoTypes to its uses clause in the interface section and copy the five IToDoData interface method declarations from the uToDoTypes unit to the public section of the data module. The class should look like this:
```
type
  TDMToDoEMS = class(TDataModule, IToDoData)
  private
    { Private declarations }
  public
  ...
```
