/**
* Declares delegated property in [ObservableHost] parent. This property is available for DataBinding
* to be observed as usual. The only caveat is that in order for binding to generate the [fieldId]
* it has to be annotated accordingly.
*
* The annotation however give very strict control over your internal fields and overall reduce
* overhead in notifying observers. (In comparison to [androidx.databinding.ObservableField])
* It helps the kotlin code to feel more,... _native_, while respecting the original functionality.
*
* # Examples:
*
* ## The most basic usage would probably be:
* ```kotlin
* @get:Bindable
* var myField by observable(defaultValue, BR.myField)
* private set
* ```
*
* ## You can use the field as public read/write, of course:
* ```kotlin
* @get:Bindable
* var myField by observable(defaultValue, BR.myField)
* ```
*
* ## Please beware that delegated property instantiates one class per property
* We discourage using simple getters via delegated properties. Instead you can do something like
* this:
*
* ```kotlin
* @get:Bindable
* var myField by observable(defaultValue, BR.myField, BR.myTransformedField)
*
* var myTransformedField
* @Bindable get() {
* return myField.transform()
* }
* set(value) {
* myField = value.transform()
* }
* ```
