Example crashes with uninitialized constant PubGrub::RubyGems (NameError)

[mensfeld]

source = PubGrub::StaticPackageSource.new do |s|
  s.add 'foo', '2.0.0', deps: { 'bar' => '1.0.0' }
  s.add 'foo', '1.0.0'

  s.add 'bar', '1.0.0', deps: { 'foo' => '1.0.0' }

  s.root deps: { 'foo' => '>= 1.0.0' }
end

solver = PubGrub::VersionSolver.new(source: source)
solver.solve # => {#<PubGrub::Package :root>=>0, "foo"=>#<Gem::Version "1.0.0">}

crashes with:

pub_grub-0.5.0/lib/pub_grub/static_package_source.rb:50:in `parse_dependency': uninitialized constant PubGrub::RubyGems (NameError)

pub_grub/rubygems ain't loaded by default.

It sounds like an easy fix, care to send a PR?
