As outlined in #49, there is a need to mimic the behavior of other
applications by interweaving positional and non-positional parameters.
This change adds the 'separate' option that will force a arg of type
[]string to only read the next supplied value.
For example, when dealing with the following arg type:
var MyArgs struct {
Pos []string `arg:"positional"`
Separate []string `arg:"-s,separate"`
}
This commit will parse the following command line:
./app pos1 pos2 -s=separate1 -s=separate2 pos3 -s=separate3 pos4
Such that MyArgs.Pos will be [pos1 pos2 pos3 pos4] and MyArgs.Separate
will be [separate1 separate2 separate3].
Unit tests for the above have also been written and are included in this
commit, as well as the addition of a section to README.md and an example
func in example_test.go.
