Adding array support in Type

[nshaheed]

This is my first-draft attempt at adding array support in Type. Currently there's some inconsistency in behavior. The following code:

[1] @=> int arr_prim[];

<<< Type.of(arr_prim).name() >>>;
<<< Type.of(arr_prim).isArray() >>>;

<<< Type.find("int[]").name() >>>;
<<< Type.find("int[]").isArray() >>>;

Prints out

"@array" :(string)
0 :(int)
"int[]" :(string)
1 :(int)

So, isArray() is working for find, but not of.

array create() from chugin does not fully work, but approving and merging PR in order to work on it further in chuck repo
