Comment(by pracine):

 Regina,

 ST_MapAlgebra() is changed to ST_MapAlgebraExpr() to clearly differentiate
 it from ST_MapAlgebraFct() which will accept a user defined function.
 Shall we keep a ST_MapAlgebra() wrapper around the simplest expression
 variant (ST_MapAlgebraExpr())?

 The ST_Mapalgebra() series will follow the FV.03 specifications discussed
 with David in Montreal.
