/**
 * DESCRIPTION:
 * <br>
 * This class represents a TmL IInstanceBuilder for Android Emulator Instances.
 * <br>
 * It is only necessary because TmL's AbstractNewEmulatorInstanceWizard could not be used
 * for Android Emulator Device Instance New Wizard implementation, so an IInstanceBuilder
 * became necessary for our Wizard implementation.
 * <br>
 * This class should be removed if TmL's Wizard begins to be used since this implementation
 * is very similar to TmL DefaultInstanceBuilder implementation and Tml's Wizard would use
 * it instead.
 * <br>
 * RESPONSIBILITY:
 * <br>
 * - Hold necessary information about a Android Emulator Device Instance for it to be
 * created.
 * <br>
 * COLABORATORS:
 * <br>
 * IInstanceBuilder: implements this interface
 * <br>
 * USAGE:
 * <br>
 * The AndroidNewWizard uses this class to hold information for creating a Android Emulator Device
 * Instance and passes it on to TmL's InstanceManager to carry on the creation.
