Use of Memory Efficient Data Structures Micro-Optimization

[CamiloFallaM]

Hi Kickstarter Team

My name is Camilo Falla and I´m a student at Universidad de Los Andes in Bogotá, Colombia studying Computer Science. I had the opportunity to take a look into the Kotlin repository in GitHub and found some micro-optimization ideas I would like to share with you. The ideas have to do with the use of memory efficient data structures. In the file TrackingClientType.kt I found that HashMaps were used but the order of the added values was always the same. In that sense, you could use an ArrayList to save thee values in the know order without having to save the keys into memory, having a better performance and memory consumption.

This would be the changes I would make on the file:

I think this micro-optimization would have a positive impact on the general application´s memory consumption. We hope you can take it into account in the future!
