 * The basic API for utilising remap-istanbul
 * @param  {Array} sources The sources that could be consumed and remapped.
 *                                For muliple sources to be combined together, provide
 *                                an array of strings.
 * @param  {Object} reports An object where each key is the report type required and the value
 *                          is report options
 * @param  {Object} remapOptions An object with options for remapping
 *               exclude?  - a string or Regular Expression that filters out
 *                           any coverage where the file path matches
 *               readFile? - a function that can read a file
 *                           syncronously
 *               readJSON? - a function that can read and parse a
 *                           JSON file syncronously
 *               sources?  - a Istanbul store where inline sources will be
 *                           added
 *               warn?     - a function that logs warnings
