Add ngeo popover component

[olivierSemet]

PR for the new ngeo component popover. The first goal of this component is to display actions capabilities for groups of layers or individual layers into the layertree but there is no limitation for other use at the moment.

Behavior of the component:

• Clicking on the anchor tag SHOULD toogle the popover
• If multiple anchors exist, only one popover can be displayed at a time
• Each anchor is linked to its own popover, meaning it exists as much popovers as anchors
• Clicking into the popover SHOULD NOT dismiss it
• Clicking somewhere else SHOULD dismiss the popover

Check the example on my GH pages here

scope should not be isolate, otherwise we can't manage inner content of the popover from upper controllers.

[fgravin]

Please try in your example to generate inner content of your popover from mainController model.
Fix scope inheritance from issues you get.

Can you try without transclude and just set ngeoPopoverCtrl.bodyElm from element first child.
Translude is actually used for something specfic that is not your usecase.
I wonder if the transclude function doesn't ensure the content is compiled though.
To test.

The layertree will change a lot so the popover will be generated and destroyed, be sure you clean everything well when they are destroyed.

Good work, I'v made some comments though.

In the end, i think that one directive should have been enough for the whole thing, your approach is good but might introduce useless complexity.

@fgravin following your advices, I pushed a new version.

[fgravin]

Looks good thanks @olivierSemet.
I'll wait the PSC validates the spec to merge it.

[fgravin]

Need to check it's needed (wait to integrate it in desktop app for that).
The element will be removed anyway, i hope jquery unregister all events when removing an element.

minor: space in front of .on

Good work.
We know that there is a potential limitation when require is not correctly handled cause of the transclude linked function usage.
But merging cause we didn't find good solution for now.
