Took data.table out of Imports, since it's in Depends

Changed RunTests() to TestGeneorama() and added documentation

Added detach_nonstandard_namespaces(), even though it's not really used.

Set several non-variables to NULL in the function definitions to avoid global namespace collisions.

Added RUnit to the NAMESPACE file to stop those RCMD CHECK complaints

Removed references to geneorama and changed to geneorama2 for now.
Merge branch 'master' of https://github.com/geneorama/geneorama2
