Global aligned box typedefs

## Detailed Description

Eigen defines several typedef shortcuts for most common aligned box types.

The general patterns are the following:

AlignedBoxSizeType where Size can be 1, 2,3,4 for fixed size boxes or X for dynamic size, and where Type can be i for integer, f for float, d for double.

For example, AlignedBox3d is a fixed-size 3x3 aligned box type of doubles, and AlignedBoxXf is a dynamic-size aligned box of floats.
