Use less dictionary object and create more classes

I can see everywhere this object `components = {'x': x, 'y': y, 'z': z, 'xx': xx, 'yy': yy, 'zz': zz}`
I would rather create a component like this:

```
class Components:
def __init__(x=0. y=0, z=0, xx=0, yy=0, zz=0):
self.x = x
self.y = y
etc...
```
after it's much easier to access the individual components `self.components.x` is much lighter than `self.components['x']` also we can add plenty of helpers inside the components class
