An option common to almost all the softwares is the Save and Load file option. Though this was a bit lower in the priority list of my work, but after getting bored of the tedious work of creating scenes to test my code everytime I made a change to it, I decided to add this option. To save a file, I decided to go with creating a .xml file which contained all the variables of the states of the models like position and scale.
The reason I chose an xml format was because the heirarchy of objects can be saved in a proper manner in an xml file.
The Load Scene option is able to read and parse these saved xml files, now allowing me to sit back and letting this load option to create a test scene for me.
