! Description:
! ------------
!> Standard kind definitions
!> wp (working precision) and iwp (integer working precision) are the kinds
!> used by default in all variable declarations.
!> By default, PALM is using wp = dp (64bit), and iwp = isp (32bit).
!> If you like to switch to other precision, then please set wp/iwp
!> appropriately by assigning other kinds below.
