The `Material` class is now an abstract class.\r\n\r\n- `MacroMaterial` contains all the same functionality as the previous `Material` class\r\n- `IsoMaterial` defines a `Material` as a set of `Isotopes`\r\n- `Isotopes` are introduced, which contain microscopic cross sections\r\n- Only major change to old functionality is `getSigmaS` has been removed from `Material`\r\n- You should now use `getSigmaSByGroup` and the new `getScatterSource` methods instead\r\n\r\nThis PR allows the definition of `Materials` to be defined on an isotopic basis, which enables self-shielding methods to be implemented and could even make comparisons to Monte Carlo easier.  Note that `Isotope` is intended to be subclassed in the future for various self-shielding implementations and scattering physics."},"comment":{"url":"https://api.github.com/repos/mit-crpg/OpenMOC/issues/comments/158800824","html_url":"https://github.com/mit-crpg/OpenMOC/pull/121#issuecomment-158800824","issue_url":"https://api.github.com/repos/mit-crpg/OpenMOC/issues/121","id":158800824,"user":{"login":"PrezNattyGibbs","id":1434947,"avatar_url":"https://avatars.githubusercontent.com/u/1434947?v=3","gravatar_id":"","url":"https://api.github.com/users/PrezNattyGibbs","html_url":"https://github.com/PrezNattyGibbs","followers_url":"https://api.github.com/users/PrezNattyGibbs/followers","following_url":"https://api.github.com/users/PrezNattyGibbs/following{/other_user}","gists_url":"https://api.github.com/users/PrezNattyGibbs/gists{/gist_id}","starred_url":"https://api.github.com/users/PrezNattyGibbs/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/PrezNattyGibbs/subscriptions","organizations_url":"https://api.github.com/users/PrezNattyGibbs/orgs","repos_url":"https://api.github.com/users/PrezNattyGibbs/repos","events_url":"https://api.github.com/users/PrezNattyGibbs/events{/privacy}","received_events_url":"https://api.github.com/users/PrezNattyGibbs/received_events","type":"User","site_admin":false},"created_at":"2015-11-22T21:25:00Z","updated_at":"2015-11-22T21:25:00Z","body":"This is something that should be worked on at some point by me, but it \nwon't be before I graduate, and who knows if it'll happen afterwards.  \nCan you archive PRs?
