#2913: support enabling / disabling storage in CarpetX

Reporter: Roland Haas Status: open Milestone: Version: Type: task Priority: major Component: CarpetX

Changes (by Roland Haas): Right now all grid variables declared in `interface.ccl` in CarpetX always have storage turned on. To reduce memory footprint for codes (and just b/c this is the expected behaviour) CarpetX shoud support Cactus' `CCTK_StorageIncrease` and `CCTK_StorageDecrease` and `STORAGE: foo`statements.
