Feat/ebay cog

[issy]

This is a price checking cog that checks the ebay website for pricing on an item. Command aliases are as follows:

• check
• pc
• chk
• price
• pricecheck Words can be filtered out of the search by using the - operator. For example: !check dell xps 15 -broken -repair The command removes outliers by selecting the 25th to 75th percentile and then returns the range, median, average and variance of that boxplot

some general comments on top: your code could do with some formatting (empty lines to make it easier to read). also, you should not be using camelCase variable names in Python, PEP-8 calls the use of snake_case instead

I'm aware of the PEP-8 naming conventions, and I disagree with them. I purposefully use camelCase for non-global variables and snake_case for functions to distinguish between the two. For me, this is much more readable and this ideology is applied to 90% of the code in this repo.
