### Vision
* function `getProperty(name: Name, inherit: Boolean, includeStyles: Boolean, includeDefaults: Boolean)`.
It gets properties of element with `name` identification.
`inherit` — toggles parent node property lookup. Null means inference from descriptor. Default is false.
`includeStyles` — toggles inclusion of. Null means inference from descriptor. Default is true.
`includeDefaults` — default is false.
* function `setProperty(name: Name, item: MetaItem?, notify: Boolean = true)`
Sets the `item` property to the element with the `name` identification. `notify` is a value which toggles the necessity of the change notification. Default is true.
### About properties
**Properties have to be set in particular order:**
* styles
* prototypes
* parent
* parent's styles
* defaults
## Inheritance
Inheritance is a very useful ability of `children` elements to get the same property in default as his parent does have (to 'inherit' it).
