Vector of Vectors to Array

VecVec_to_Array

"""
# Convert a vector of vectors to an array
This function assumes that each vector is the same length;
i.e.
v1 = [ [1,2], [2,3], [5,6] ] # this is fine
v2 = [ [1,2,8], [2,3], [5,6] ] # this is not fine

Example of usage:
```
vv = [[1,2,3], [4,5,6], [7,8,9],[12,13,14]]
println("num components in each vector = ", length(vv[1]))
println("num of vectors = ", length(vv))
vecvec_to_array(vv)
```
