Item Trade Shops

This plugin aims to provide players with a nostalgic experience, bringing back the classic sign shops, with a twist. Inspired by 'HermitCraft', I found server economy gameplay exciting when tangible items, such as diamonds, were used to purchase items rather than intangible economy currency. The sign shops allow players to fill a single chest or trapped chest with items they wish to sell. If another player wishes to buy this item, all they need to do is right click the sign, with the number of cost items required inside their inventory. Imagine villager trading but without the awkward stare, or living creature, involved and the person who owns the store can set the prices.

Want to sell 16 apples for one diamond? Sure!
Want to sell a stick for a beacon? Sure! (good luck)

Commands are also included so that if an item name cannot fit on a sign or hanging sign, just by simply looking at the sign and executing the command can fix this!

This is my very first plugin and I cannot guarantee zero bugs, so if you find any, please let me know.
