* An IndexedSourceMapConsumer instance represents a parsed source map which

* input.
*
* The first parameter is a raw source map (either as a JSON string, or already
* parsed to an object). According to the spec for indexed source maps, they
* have the following attributes:
*
* - version: Which version of the source map spec this map is following.
* - file: Optional. The generated file this source map is associated with.
* - sections: A list of section definitions.
*
* Each value under the "sections" field has two fields:
* - offset: The offset into the original specified at which this section
* begins to apply, defined as an object with a "line" and "column"
* field.
* - map: A source map definition. This source map could also be indexed,
* but doesn't have to be.
*
* Instead of the "map" field, it's also possible to have a "url" field
* specifying a URL to retrieve a source map from, but that's currently
* unsupported.
*
* Here's an example source map, taken from the source map spec[0], but
* modified to omit a section which uses the "url" field.
*
* {
* version : 3,
* file: "app.js",
* sections: [{
* offset: {line:100, column:10},
* map: {
* version : 3,
* file: "section.js",
* sources: ["foo.js", "bar.js"],
* names: ["src", "maps", "are", "fun"],
* mappings: "AAAA,E;;ABCDE;"
* }
* }],
* }
*
* The second parameter, if given, is a string whose value is the URL
* at which the source map was found. This URL is used to compute the
* sources array.

*
* A single static vnode can contain stringified content for **multiple**

* container element and insert all the nodes in place. The call must also
* provide the number of nodes contained in the chunk so that during hydration
* we can know how many nodes the static vnode should adopt.
*
* The optimization scans a children list that contains hoisted nodes, and
* tries to find the largest chunk of consecutive hoisted nodes before running
* into a non-hoisted node or the end of the list. A chunk is then converted
* into a single static vnode and replaces the hoisted expression of the first
* node in the chunk. Other nodes in the chunk are considered "merged" and
* therefore removed from both the hoist list and the children array.
