| ## Describe your changes | ||
|
|
||
| ## Checklist before submitting your PR | ||
| - [ ] This PR implements a single change (one new/modified Tool, or a set of changes to implement one new/modified feature) | ||
| - [ ] This PR alters the minimum number of files to affect this change | ||
| - [ ] If this PR includes a new Tool, a README and minimal demonstration ToolChain is provided | ||
| - [ ] If a new Tool/ToolChain requires model or configuration files, their paths are not hard-coded, and means of generating those files is described in the readme, with examples provided on /pnfs/annie/persistent | ||
| - [ ] For every `new` usage, there is a reason the data must be on the heap | ||
| - [ ] For every `new` there is a `delete`, unless I explicitly know why (e.g. ROOT or a BoostStore takes ownership) | ||
|

| Attach any validation or demonstration files here. You may also link to relavant docdb articles. |
