Delete all links/plots using 'update' event

[Indigo744]

Allows to refresh the entire map (#104)

Usage:

var deletedPlots = "all", 
opt = {
    animDuration : 1000,
    deletedLinks : "all"
    };

$(".mapcontainer").trigger('update', [{}, {}, deletedPlots, opt]);

Why haven't you wrote "plots = {};" for resetting the object ? Is your way faster ?

[Indigo744]

Good question. I actually did some research because I wasn't sure. Turned out = {}is not the best way to do it: it will keep any referenced array as is. See this SO answer: http://stackoverflow.com/a/1232046

Hmm, in any case, I think it shouldn't work properly because the variables plots and areas are objects and not arrays, so they shouldn't have the 'length' property.

Moreover, by using this way for resetting an array, I wonder how the garbage collector behaves ?

[Indigo744]

Oh right, I don't know why I supposed that plots or links were array! They are object! I will change it.
For array, setting length to 0 will shrink the array size automatically.
