Makefile Included and TIFF input

TIFF files are now used as input in this version. Both 8-bit and 16-bit
files can be used, but 16-bit files are going to be rescaled to 8-bit.
We are now using a Makefile to compile this version.

Main things to be done:

1. Validate Fourier approach
2. Implement periodic corners
3. Remove periodic borders when running discrete approach
