docstring example for `@LVector` appears to be incorrect

[pcjentsch]

The example given in the docstring does not seem to work.

help?> @LVector
  @LVector Type Names


  Creates an LArray of dimension 1 with eltype and undefined values. Length is via
  the number of names given.

  For example:

  b = @LVector [1,2,3] (:a,:b,:c)


julia> b = @LVector [1,2,3] (:a,:b,:c)
ERROR: TypeError: in Type, in parameter, expected Type, got a value of type Vector{Int64}
Stacktrace:
 [1] top-level scope
   @ ~/.julia/packages/LabelledArrays/ti1TC/src/larray.jl:177
