NamedTupleTools is a small package that makes doing a few things with `NamedTuples`

a bit easier.

*(Julia v1.0)*

```
using NamedTupleTools
julia> namedtuple(:a, :b, :c)(1, 2.0, "three")
(a = 1, b = 2.0, c = "three")
#=
namedtuple( name1, name2, .. )
namedtuple( (name1, name2, ..) )
where the `names` are all `Symbols` or all `Strings`
Generate a NamedTuple prototype by specifying or obtaining the fieldnames.
The prototype is applied to fieldvalues, giving a completed NamedTuple.
=#
julia> ntproto = namedtuple( :a, :b, :c )
NamedTuple{(:a, :b, :c),T} where T<:Tuple
julia> nt123 = ntproto(1, 2, 3)
(a = 1, b = 2, c = 3)
julia> ntAb3 = ntproto("A", "b", 3)
(a = "A", b = "b", c = 3)
julia> isprototype(ntproto)
true
julia> isprototype(nt123)
false
julia> delete!(nt123, :a) === (b = 2, c = 3)
true
julia> delete!(nt123, :a, :c) === delete!(nt123, (:a, :c)) === (b = 2,)
true
julia> delete!(ntproto, :b) === namedtuple(:a, :c)
true
julia> ntproto1 = namedtuple(:a, :b);
julia> ntproto2 = namedtuple(:b, :c);
julia> merge(ntproto1,ntproto2)
NamedTuple{(:a, :b, :c),T} where T<:Tuple
```
