Add support for array types

[apavlo]

A couple of the teams in the class need to store arrays in the catalog. We currently have array types in our code but there is no implementation. This is something that we need to add this semester.

Hi Andy,
is src/type/array_type.cpp or src/include/type/array_type.h the array type you referring to?

[apavlo]

Yes

[YuanLuo1]

But I think it is implemented already?

[apavlo]

Is it completed? Is there test code? Is there any part of the system actually using it?
