GAMS doesn't recognize "acos" #8

Hi, GAMS.jl has a problem with 'acos'. In GAMS (as opposed to Julia-JuMP) it is called arccos. Might there be a translation problem? See problem line:

    @NLexpression(DPVI, V̂[i=SN, j=Sdeg], coefs[j] * cos((j - 1) * acos(dz * (kPlus[i] - extkmin) - 1)) )

Absolutely! Thanks for reporting this issue. Will be fixed shortly.

Has been fixed with GAMS.jl version 0.2.2 (available in package manager very soon). Also added support of asin, atan, mod and sign. Thanks again for pointing out this issue!
