GlobalMapper - batch reproject and export geotif to ecw

A simple GlobalMapper script that iterates through all the tiff files in a specified directory, and exports them to ecw in EPSG 2180, 3857 and 4326.

//Exports all the tif files found in the source dir to ecw.
//Reprojects the data to 2180, 3857 and 4326 and the exports it to the appropriate folders
