use ensure_resources to handle multiple physical_volume in a volume_group
(dependency in Modulefile is only stdlib 2.x, although 4.1 is required
for this new behaviour.)
declare which stdlib version is needed for multiple pv
With extents being a property we need methods to manage it. I don't know how to do that, so make it an parameter.
Add stripes and stripesize params
Fix syntax error
Update lvm_spec to support stripes and stripesize.

Merge pull request #49 from genome-vendor/master

Extents doesn't work as a property, no method implemented. Also, add stripes and stripesize.
Prepare 0.2.0 release.
Merge pull request #50 from apenney/020-release

Prepare 0.2.0 release.
Use fully qualified volume paths
Implement 'instances' method for all LVM resources

This method makes it possible to use constructs like:
  resources { 'physical_volume': purge => true, noop => true, }
  resources { 'logical_volume':  purge => true, noop => true, }
  resources { 'volume_group':    purge => true, noop => true, }
Implement empty 'extents' method

It is required by 'instances' method.
There is no simple way to get LV size in extents,
so leave it empty for now.
Set default LV unit size to MB
