changing KiD variables to dry variables used in libcloud
passing the second argument to th_dry2kid, th_kid2dry, rho_kid2dry; changing rhod_Cx/rhod_Cz - this is not finished
changing type conversion in save_dg - now there is a copy of array (keyword argumend does not work for older numpy)
Adding assert to check if dx/dz are equal in whole domain
wip on saving binned spectra
using constants from libcloud
using exceptions handling for astype fucntion
small cleaning in the calculation of th tendency (i believe it was confusing)
passing dt to the python function micro_step
adding a comment to global
wip on outputting binned spectra
finishing up binned spectrum output; restoring original domain size
adding assert for dt
moving calcualtion of rho_d to the first time step IF
restoring original domain size
changind len(arr.shape) -> arr.ndim; more comments (as per remarks from Dorota)
