allow template function eq to compare equivalent types
Added Test and Benchmark

Had an interesting finding, wen comparing two []byte comparing strings
a stack exception happens also removing the default case did't slow
things down. It seems the compiler optimizes that by itself.
finishing touches

changed the handling of a and b being of similar but uncomparable types
to avoid errors being thrown in vain.
and added rune types so ppl can use 'a'=="a" and {'a','b'}=="ab" and so
on
although it became alot of code for such a utility function i think i
got ir right now.
changed to reflect all the input by robfig

ints are int64, uints are uint64, floats are float64 and []byte is a
string when compared to a string
equal types are handled via reflect.DeepEqual
Tests are more concise and readable now
added checkbox helper
