Genotype preservation

[gliechtenstein]

$node.$snapshot() returns its genotype. Used for serializing/deserializing a cell.

Example:

c = {
  $cell: true,
  $type: "div",
  class: "container",
  $init: function() {
    for(var i=0; i<5; i++) {
      this.$components.push({$type: "div", class: "row", $text: i})
    }
  },
  $components: []
}

var gene = document.body.querySelector(".container").$snapshot();
// 'gene' contains the contents of the variable c;
