Some better things

[summerstyle]

• [x] separate the tree library (tree.css, tree.js)
• [x] replace ids in css with classes (because it is possible to add two trees at one page)
• [x] add library docs
• [x] replace an icon with beautiful one
• [ ] add support for color themes
• [x] refactor CSS-styles for tree. Class names should be more specifiсally, because now it is a library, and it may use in various pages, including pages with same class names. And now, markup is ugly(
• [x] add beautiful font 'PT Mono' from google.fonts
• [ ] add feature with creation of filter function from textarea by new Function
• [x] add feature with selecting some nodes by filter function
• [x] add sorting for object keys
• [ ] add highlighting for expanded nodes
• [ ] add search by js-path (for ex. root["phoneNumbers"]["0"]["type"])
• [x] add displaing js-path for each node by click? And copy this path to search form (for editing path and finding similar or child nodes)
• [ ] add expanding of root node by depth (count of descendants levels)
• [ ] add expanding for all tree recursively by some function (for ex., expand all nodes with some count of children) Fix docs!
• [ ] Add unit-tests for library
• [ ] Add custom templates for values (by matcher + handler). For example:

• strings which starts with "http://" displays as link
• nodes with label "color" displays with circle of color in value at right side
• numbers displays as "123 000 000" with spaces
• nodes with label "image" by mouseover shows images preview etc.

• [ ] Add "find and get as array" feature. Not nodes marks, only result displays as array.
• [ ] Change app.js' styles and class names. Now this is very ugly!
