Hello,

I am quite new to Julia and I would like to use the GSL package 
<https://github.com/jiahao/GSL.jl> in order to find the roots of a 
multidimensional system of equations.
According to the reference manual 
<http://www.gnu.org/software/gsl/manual/html_node/Example-programs-for-Multidimensional-Root-finding.html#Example-programs-for-Multidimensional-Root-finding>,
 
I have to allocate memory to the solver. But to do so, I have to give a 
pointer to a fslover_type. Indeed, methods(multiroot_fsolver_alloc) prints 
out:
*multiroot_fsolver_alloc(T::Ptr{gsl_multiroot_fsolver_type},n::Integer) *

But I cannot find any fsolver_type that could be used. The only one that is 
given is: *gsl_multiroot_fsolver_hybrid* and it is not defined. I was 
thinking about creating a link to the c libgsl. But I from that point I am 
completely lost. 

Besides, I don't know how to convert julia vector to gsl vector as 
mentionned in issue #12 <https://github.com/jiahao/GSL.jl/issues/12>. 
(gsl_vector_set has been deleted)

Thanks for helping,

AM.
