CELL2VEC - Concatenate cell elements to a vector
V = Cell2Vec(C)
INPUT:
C: Cell array of any size and types:
DOUBLE, SINGLE, (U)INT8/16/32/64, LOGICAL, CHAR.
The elements of C can have different sizes.
OUTPUT:
V: [1 x N] vector of all elements.

EXAMPLE:
C = {1, 2; 3, 4};
V = Cell2Vec(C) % [1, 3, 2, 4] columnwise order
M = reshape(V, size(C)) % [1, 2; 3, 4]

This C-Mex is up to 5 times faster than CAT(C{:}), HORZCAT or CELL2MAT.
