Attempt at warnings.

Attempt at fixing some of the warnings.

[acroy]

This looks good to me. Could you try to address also the "Union" warning (probably using Compat)?

[amitjamadagni]

@acroy there seems to be a problem with methods of the formfunction(arg::@compat Union{arg_1...}...) leading to seg fault on the nightly release.

To get rid of the last warning, it might be sufficient to move the conflicting line 177 before line 175 in quarray.jl?

[acroy]

Looks good to me. @jrevels : Any idea regarding the last warning?

[jrevels]

You mean:

julia> using QuBase
WARNING: New definition
    convert(Type{#QV<:QuBase.AbstractQuArray{B<:QuBase.AbstractBasis, T<:Any, 1}}, #DV<:QuBase.CTranspose{B<:QuBase.AbstractBasis, T<:Any, 1, Q<:Any}) at /Users/jarrettrevels/.julia/QuBase/src/arrays/quarray.jl:175
is ambiguous with:
    convert(Type{#T<:Any}, #T<:Any) at essentials.jl:59.
To fix, define
    convert(Type{_<:QuBase.CTranspose{B<:QuBase.AbstractBasis, T<:Any, 1, Q<:Any}}, _<:QuBase.CTranspose{B<:QuBase.AbstractBasis, T<:Any, 1, Q<:Any})
before the new definition.

I'd just remove line 175. It's not really doing much anyway. The conversion zoo can likely be made simpler if we make the move to using traits instead of type aliases for identifying states/operators/etc.

@jrevels : Ok, you are probably right. It is not worth to fight for this error message. @amitjamadagni : Could you remove the offending line?

[amitjamadagni]

@acroy this is also ready !

[acroy]

Nice!
