ramanujansrinath/xper-master ? reverse-engineered prompt

I want this repo turned into something I can actually open and run without guessing. It looks like a Java project with a core Xper app plus several related modules and example versions for things like choice, match, and fixation change tasks. Please wire it up so the main modules build cleanly, the example apps can be launched, and it is obvious which example is for what.

If anything is missing, use sensible defaults and look up current docs online if you need to. Add a simple way to start the examples, make the setup consistent across the modules, and fix any broken references or build issues you find. I would also like a short getting started guide in plain English that tells me what each top level module is, which ones are examples versus core code, and the exact steps to run a basic demo from a fresh machine.

Basically, make this feel like a usable multi module Java workspace instead of a pile of folders.
