Fix map collection

[jleeothon]

Two examples here:

• Printing a map

Source:

map{int16, string} hakkaNumbers: 1: "yit", 2: "gni", 3:"sam";
"${hakkaNumbers}";

Expected output:

{1:yit, 2:gni, 3:sam}
yit

Actual output:

{0,0,0}

• Accessing an element using bracket notation

Source:

map{int16, string} hakkaNumbers: 1: "yit", 2: "gni", 3:"sam";
"${hakkaNumbers[1]}"

Expected output:

yit

Actual output:

Access violation
[1] <main> (example.hyve:2)
