MDS type not defined

[jpfairbanks]

The function mds(D::Array{T,2}) at DimensionalityReduction/src/mds.jl:22 returns a type MDS(X, D, k) which is not defined in the package. The typedef was removed in commit cbbbfcab8f19e891e77380cdd12eed8ddee50e13. Was this an accident or an intended removal of a feature?

Here is a diff of my ~/.julia/DimensionalityReduction/src/types.jl to add the type back in. The file test/mds.jl still does not work because Error: dist not defined.
