Woo_Directive_Context{} │ WC 1.0

This is a data structure to hold the current context.

Whenever encountering a woo-context directive, we need to update the context with the data found in that directive. Conversely, when "leaving" that context (by encountering a closing tag), we need to reset the context to its previous state. This means that we actually need sort of a stack to keep track of all nested contexts.

Example:

<woo-context data='{ "foo": 123 }'>

<!-- foo should be 123 here. -->
<woo-context data='{ "foo": 456 }'>
	<!-- foo should be 456 here. -->
</woo-context>
<!-- foo should be reset to 123 here. -->

</woo-context>

Хуков нет.
