* Add WCS GeoTiff elevation support * Fix parameter documentation * Revert addition of read from array method * Add capability to construct GeoTiffReader from URL or ArrayBuffer - Modifies ElevationModel data retrieval handling for GeoTiffs * Revise GeoTiffReader API - Constructor takes ArrayBuffer and parses - Provides synchronous image a data retrieval - Add utility method with asynchronous XML HTTP Request * Clean up variable naming, formatting, and other conventions * Update naming and refactor callback to match library convention * Remove old comments * Fix one property accessor * Provide full xhr object on failure and success callbacks * Add grayscale and rgb retrieval unit tests * Add logging message
