+-  Changed Quantity to Tensor that can use any shape and is a single @Vector.
+   Point being to add WebGPU easily from this.
+   Scalr suffer in performance tho, I will work on that
+
+Maybe I can do a jupiter like web interface with cells to make Dim analysis
+I could:
+  - Use cells with a toy language
+  - A nice debugger to display current variables with dimensions, type and value
+  - Realtime error (I try to compile at change, display error on the cell)
+  - Integrate a small graphic API that use Raylib canvas
+  - COuld generate template at comptime =o
