Spherical Harmonic Expansion routine in python+fortran

• sht_py: pure python functions
• sht_ctype: functions using ctype (faster and parallerized)

You just need numpy and scipy.

please just make at sht/ directory

make

You might need to set enviroment variable and increase stack size

export OMP_STACKSIZE=512000
ulimit -s unlimited

The number of threads is defined as

export OMP_NUM_THREADS=4

For MacOS X, it does not work and we cannot use large size of quantities for the transformation.

please see help(sht_py) and help(sht_ctype)
