    Go: Split a string of comma-separated key/value pairs. Commas may be embedded in a given key/value pair.
    I'm fairly new to the Go language and am looking for a way to split a variable length string into a map where the key/value pairs (all strings) are comma separated and only some variations of the string may have multiple Comma and/or colon in the given key/value pair. For example: String 1 variant keyword 1 = value 1, keyword 2 = value 2, keyword 3 = value 3, value 4, value 5, keyword 4 = value 6... String 2 variant keyword 1=value1,keyword2=value2,keyword3=value3,value4,value5:value6,value7,value8,keyword4=value9...where "..." reflects to the fact that there will be a variable # key/value pair. I hope to end up with a map like this: map[string]s
