WCPS1.5_Difference values between same interval from coverage[scalar] and coverage[expression]

[Bang Pham Huu]

Below is another example which returns 2 different values but same scalar interval (c[j(0)] and c[j(0+0)])

+ This returns 36

http://localhost:8080/rasdaman/ows?service=WCS&version=2.0.1&request=ProcessCoverages
&query=for c in (mr) return max(c[j(0)])&wcpsVersion=2.0

+ This returns 15

http://localhost:8080/rasdaman/ows?service=WCS&version=2.0.1&request=ProcessCoverages
&query=for c in (mr) return max(c[j(0+0)])&wcpsVersion=2.0

The problem with this ticket (also with WCPS 1.0) due to it does not calculate the expression in petascope and convert to grid coordinate (e.g: c[j(0)] = c[210] in grid coordinate), then c[j(0 + 0)] = c[0] in grid coordinate.

Ticket ​http://rasdaman.org/ticket/1239 will fix this and in this ticket will need to test it by a test case.

In current WCPS 1.5, we don't support a numeric expression inside interval (e.g: c[i(1+1)]) but if it has the axis iterator variable then no problem (e.g: c[i($px + 1)]).
