KernelDensity.jl rolled its own range generator which suffers from similar flaws as Base's linspace prior to being fixed in JuliaLang/julia#18777. This closes #39. @andreasnoack @simonbyrne. This needed for GiovineItalia/Gadfly.jl#1157

Tests are passing on 0.6 and the failures on the nightlies appears unrelated.

linspace is deprecated in 0.7, so this should be Compat.range(lo, stop=hi, length=npoints)

Good catch.
