Replace arrays with dictionaries in Tophat.py

[dotcomstar]

If you use Python dictionaries (the equivalent of HashMaps in Java) to keep track of Tophat traits in Tophat.py then it might be a clearer way to grab the side and direction than pulling from an array.

Theoretically, you could do something like

Old:

Incredibots2020/Legobot/Tophat.py

Lines 21 to 22 in eb87e14

	self.side = location[0]
	self.direction = location[1]

New:

self.side = location["side"]
self.direction = location["direction"]

Second, if you change the static variable all_tophats from an array into a dictionary, then you would be able to reference tophats by their names. The calling syntax could look something like this:

Old:

all_tophats[0]

New:

all_tophats["left"]

Dictionaries work by mapping one piece of data to another in "key-value pairs." It's a little bit like magic but bear with me. In this case, we could automatically link an object's name to anything we want. Right now, we just append self to the next array slot in all_tophats. This can be nice to count the number of total tophats, but makes finding the exact one you want a pain because you don't know which number is associated with which tophat. Instead, we could put the same data self into a dictionary so that it is mapped to the string representing its name. Essentially, you would then be able to search for the tophat you want by its name.
