RasdaPy_Create some other types which corresponds to rasql

[Bang Pham Huu]

RasdaPy needs to have some other classes which corresponds to types in rasql to store the value from query, e.g: sdom©, sdom©[0], sdom©[0].hi,…instead of just a string "[0:250, 0:210]" or array of strings ["0:250", "0:210"] which user needs to parse manually.

so it can be array: MARRAYTYPE
it can be a point like [1, 2]: POINTTYPE
SINTERVALTYPE like 1:2
MINTERVALTYPE like [1:2, 2, *:1] 
OIDTYPE: number  
otherwise it's a scalar, composite (e.g. 3-bands {1, 2, 3}), or primitive (e.g. 5)
