Tool for reversing the order of the starting gates

How this is used: Copy all the lines in the file "timing_gates" that are in between "startinggate:" and "checkpoints:" then paste them into the input box below. When the new output is generated, go ahead and replace your current code in the "timing_gates" file with the new code (always keep a backup of what is working, it's a good practice). The text that you are supposed to copy/paste into the input box should look similar to this:

[639.320007 0.000000 323.690002] -2.851536
[643.152954 0.000000 322.545959] -2.851536 
[646.985840 0.000000 321.401947] -2.851536
