Added floquet project

C strings/compliant version plus more

The driver has been reshaped in order to:

• use C compliant NULL initialization of C strings
• better search of unused ASCII characters for options with only long-format (no short-format)
• repaired the internal makefile very useful for debugging.
• use integer short option strings instead of character kind. In C there is no difference and the code was giving lots of warnings when used with nvfortran.
• added a no_bin element in options_struct. This can be used to specify that a given option does not apply to specific bins. Easier to use when a project uses just few runlevels.
