Neuron graphic rendering

[jlrandulfe]

In order to make the neuron more meaningful for the user, the graphical model should be improved. This will more likely imply doing modifications in the Rana c++ core. The agent should be enhanced with the following features:

Soma

• [ ] The graphical representation of the soma may include, besides the central dot that already exists, a bigger shape surrounding it.

Neuron axon links:

• [ ] Besides the PositionX and PositionY, it shouldinclude a root position, axon length, and angle. Every point belonging to the segment from the root to the tip should be rendered with a different colour in the map.

• [ ] When the agent moves, the segment moves as well. The movement has to be constrained in a way that the root is always linked to the tip of the previous link (Maybe a kinematics model is useful here)

Growth cone

• [ ] It may be represented as a circle-like shape at the end of the last axon link.

At first, it was tried to colour the map directly from lua, but it doesn't seem feasible. It would be very inefficient, as every time the neuron shapes varies, the map has to be coloured again (deleting the previously coloured shape as well)
