This taks focused on manual tests of this bux package which I primarily conducted using provided examples and in connection with bux-server.

Along with these tests I made the following changes:

• Adjusted the examples
• Removed unused public functions (unused by bux & `bux-server) with several exceptions - if I determined that a function might be usefull for a potential user of our package, I retained it.
• Performed staticcheck and fixed issues detected by this tool
• Performed golint and fixed most of the errors
• Fixed spelling issues
• Added utils.byte_array.go file because of the conversion from byte array to string and vice versa was previously done in a buggy way
