/**
* An IndexedSourceMapConsumer instance represents a parsed source map which
* we can query for information. It differs from BasicSourceMapConsumer in
* that it takes "indexed" source maps (i.e. ones with a "sections" field) as
* input.
*
* The only 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;"
