argv types (XTRACT_FLOAT, XTRACT_INT) and pass the correct data type
to the xtract[]() function
- Added xtract_flatness_db() details to descriptors.c
- Fixes to tonality and xtract_subbands descriptors
- Added Pd examples for 'subband mean' and tonality calculated using subbands

Added new extraction function: xtract_subbands()

documentation and error checking to avoid problems
- Added xtract_is_denormal() helper function and XTRACT_DENORMAL_FOUND
return code
- Replaced all instances of log, sqrt, exp etc. with respective
floating point counterparts (logf etc.)
- Added check for architecture endianness to configure script
- Bug fix to PD example, now no longer crashes if no arguments are
given
- Minor documentation updates

Removed fftw_plan from xtraction functions. Created new init function xtract_init_fft() for creating plans, which have global scope. Updated examples to reflect the change. New configure option: --with-fft_optimisation (0 = FFTW_ESTIMATE, 1 = FFTW_MEASURE, 2 = FFTW_PATIENT).
