Expose legend model in layer views

[alonsogarciapablo]

This is part of #101. It exposes a legend model on layers/sublayers so that users can do some custom things, such us:

• Changing the template of the legend.
• Customizing the title of the legend.
• Showing/hiding the title of the legend.
• Getting/Setting the items that are displayed in the legend.
• Showing/hiding the legend.

@javisantana what do you think?

Sweet 👍

How would this be used to create the default legend?

Something like this?

var legend = new cdb.geo.ui.Legend({ model: layer.legend })

@knownasilya You can basically manipulate the legend models (layer.legend) to customize your legends. Once this is relased, you will be able to get/set the items, customize the template, show/hide a legend, etc.

Would love an example of this being used

Do I have to use createVis, or can this be accessed from createLayer as well?
