Parses out base64 VLQ encoded mappings.
npm install parse-base64vlq-mappingsParses out base64 VLQ encoded mappings.
The code is mostly lifted from mozilla's source-map module in order to separate
out the parse function into its own module.
``js
var parse = require('parse-base64vlq-mappings');
var mappings = parse('AAAA;AACA;AACA;AACA;AACA');
console.log(mappings);

[ { generated: { line: 1, column: 0 },
original: { line: 1, column: 0 } },
{ generated: { line: 2, column: 0 },
original: { line: 2, column: 0 } },
{ generated: { line: 3, column: 0 },
original: { line: 3, column: 0 } },
{ generated: { line: 4, column: 0 },
original: { line: 4, column: 0 } },
{ generated: { line: 5, column: 0 },
original: { line: 5, column: 0 } } ]
Main intended use is either for testing generated mappings or to add offsets to existing mappings.
Therefore is is assumed that all mappings relate to the same generated/original file, i.e. only information about
generated line and column vs. original line and column is preserved.
