Changes

• Removes reccomendation of pairs() and replaces it with generic iteration
• Renames the deepCopy function to deepClone
• Makes the deepClone function use table.clone
• Fix deepFreeze erroring if a value is already frozen
• Explains dot indexing for dictionaries .key
• Removes warning for using ipairs to iterate over a dictionary, as ipairs is unnessary to use unless wanting to stop at the first nil in a array with holes (a behavior that is very rarely desired)

The last one is a bit iffy so feel free to reverse it. Also unsure if the wording for Write to dictionaries is the best, but I think the added warning clears it up.
