Added lock to move the card on an axis

[andre991]

Added the Axis enum to allow card to move from a unique axis or both. Issue #64

@mac-gallagher I added an enum to drag card from a unique axis.

Hey @andre991 thanks for opening this pull request. I tried the same thing after you opened #64, but the cards behave unexpectedly in the example project. If you drag horizontally, the card slides downwards because there is a rotation angle on the card animation options. It may require some changes to card.layer.anchorPoint. Let me know if you figure anything out

Hi @mac-gallagher I will test this in example project, but in my project the animation looks normal. The rotation is work perfectly for me. You have an gif to share?

Here's what a horizontal swipe looks like with Axis.all (current behavior in Shuffle). Notice how the center of the card stays on the horizontal axis

and here is a horizontal swipe with Axis.horizontal:

Hi @mac-gallagher, sorry for the delay.

The axis is to block card movement for other Axis.

Look at the mouse movement.

[andre991]

Axis.all The card movements in all axis.

[andre991]

Axis.horizontal The card movements only in horizontal axis(see the mouse).

Hey @andre991 yes I understand - your change blocks the card movements in the specified directions just fine. However, I would expect everything else to remain the same. The card follows different trajectories for a horizontal drag with Axis.all and Axis.horizontal. They will need to be the same before merging this change
