Odd indexbase behavior

[fcarlosjr]

Hi Michael,

I'm having a hard time trying to understand a weird behavior when using some custom Indexbase with my containers. To illustrate that, lets suppose I define two types of GeMatrix: a
GEMatrix6 with IndexBase 6, and a GEMatrix1 with IndexBase 1. Suppose I create
2 matrices of each type: GEMatrix6 A, and GEMatrix1 B. What is bothering me is
that if I do the following:

GEMatrix1 B = A;

the matrix B assumes the IndexBase of A (6), despite being of type GEMatrix1
(with IndexBase 1). The same goes if I do the following:

GEMatrix1 B;
B = A;

By contrast, if I do the following:

GEMatrix1 B(A.numRows(), A.numCols());
B = A;

then the matrix B assumes the IndexType of its type (1), as I expected in the
first place for all cases. Is this different behavior normal?
