Convert a 1-dimensional indexed vector of real spherical harmonic coefficients
to a three-dimensional array.

Usage
-----
cilm = SHVectorToCilm (vector, [lmax])

Returns
-------
cilm : float, dimension (2, lmax+1, lmax+1)
    The 3-D arrary of output real spherical harmonic coefficients.

Parameters
----------
vector : float, dimension ( (lmaxin+1)**2 )
    The input 1-D indexed array of real spherical harmonic coefficients.
lmax : optional, optional, default = lmaxin
    The maximum degree of the output coefficients.

Description
-----------
SHVectorToCilm will convert a 1-dimensional indexed vector of real spherical
harmonic coefficients to a three-dimensional array. The degree l, order m, and i
(1 = cosine, 2 = sine) corresponds to the index l**2+(i-1)*l+m.
