CopperTileMapper

This plugin provides functionality to create a tile map using a selected texture in the CopperCube game engine.

It allows the user to specify the number of rows and columns for the tile map and generates a grid of planes with the specified texture.

Additionally, the plugin supports snapping selected nodes to a grid and rounding rotations to 90 degrees when holding Alt and Z.

Functionality:

- createTileMap(): Prompts the user for the number of texture rows and columns, creates a grid of planes with the selected texture.

- snapNodeToGrid(): Snaps the selected scene node's position and rotation to the nearest grid point (assumes a grid size of 5),

and rounds the rotation to the nearest 90 degrees when holding Alt and Z.

Usage:

- Call createTileMap() to generate a tile map with specified rows and columns.

- Call snapNodeToGrid() to snap the selected node's position and rotation to the grid (Alt+Z).
