Speed up code

Currently there is a brute-force approach to identifying stars across images. It looks like this is also done multiple times as the analysis continues. I am proposing doing the matching once at the start of the process and using this master list for the rest of the code.

I have done a lot of this..... it is much faster.... but I can do more. I MUST do more. After RTSRE. It is very much faster now though
