X[i] Return the i'th coefficient from the multivector X

[orat]

e.g. if X is an multivector and i is a an integer < 32 than X[3] is an multivector with only a value !=0 at index 3

This idea is incompatible with the usage of the brackets to define multi-arrays of multivectors. Multidimensional arrays are needed to combine CGA with linear algebra.

Better add a build-in function: scalar(i) to get a multivector representing the coefficient of the given index as scalar. An integer type is needed or only "1", "2",... fix int numbers are allowed.
