#2758: conditional read/write statements

Reporter: Samuel Cupp Status: new Milestone: Version: Type: enhancement Priority: minor Component: Cactus

Currently, if a function reads or writes variables only under certain conditions, proper scheduling within the schedule.ccl would require duplicating the entire function schedule for every possibility. As a simple example,

``` if(CCTK_EQUALS(EOS, "Tabulated")) { schedule func at bin { LANG: C READS: var1 WRITES: var2, var3 } } else { schedule func at bin { LANG: C READS: var1 WRITES: var2 } } ```

Instead, having the ability to set these conditionals within the function scheduling like

``` schedule func at bin { LANG: C READS: var1 WRITES: var2 if(CCTK_EQUALS(EOS, "Tabulated")) { WRITES: var3 } } ```

would make this scheduling much more compact **and** more readable.
