added a Matlab function that converts images to one envi file Just some notes Dr. Mayerich: 1. The images should be stored in a struct to be loaded in the function. 2. I cast any type to float. So, if we have some files of 'double' type, we might loose some accuracy. 3. I just included the 'samples', 'lines', 'bands', 'header_offset', 'file_type', 'data_type' and 'interleave' parameters in the header file. Please let me know if you need any other things to be added to the function. See merge request !6
