Detailed Description

This is the superclass of the array and vector type classes.

Both of these represent "arrays" in memory. The array type represents a specifically sized array, and the vector type represents a specifically sized array that allows for use of SIMD instructions. SequentialType holds the common features of both, which stem from the fact that both lay their components out in memory identically.
