`joy_mapentityrounder.py`

### What it is for
Scans `.map` files in the script’s own folder and rounds values in `"origin"` entity keys to the nearest integer.

This is useful for cleaning up entity origin coordinates in map files.

### Usage
```bash
python joy_mapentityrounder.py
```

### Arguments
None.

### How it works
- Looks in the same directory as the script.
- Finds all `.map` files there.
- For lines matching:
```text
"origin" "x y z"
```
it rounds each numeric value with standard integer rounding.

Example:
```text
"origin" "127.6 64.2 -31.8"
```
becomes:
```text
"origin" "128 64 -32"
```

### Save behavior
For each file:
1. It prints all changed lines.
2. It shows totals.
3. It asks:
   - `Do you want to save the changes? (yes/no):`

### Output
Edits the original `.map` file only if you confirm.
