WCPS not case sensitive on some keywords

[Piero Campalani]

Despite the correct grammar definition in petascope.wcps.grammar.wcps.g, some WCPS keywords are case-sensitive:

for c in (eobstest) return crsset(c) -> Invalid coverage Expression, next node: crsset
for c in (eobstest) return crsSet(c) -> OK

for c in (eobstest) return ideNTifier(c) -> Invalid coverage Expression, next node: ideNTifier
for c in (eobstest) return ideNTifier(c) -> OK

This is apparently affecting metadata expressions only, but I did not make an exhaustive test.

for c in (eobstest) return encode(
-  add (c[Lat(0), Long(51)])
+  aDd (c[Lat(0), Long(51)])
, "csv")

-> OK

Case-sensitivity to all keywords should be evaluated, and test(s) added.

There is most probably an equals test somewhere in the WCPS code itself, rather than in the parser.

[Piero Campalani]

Yes exactly, this ticket must be all about some replacement of equals to .equalsIgnoreCase.
