reads and builds a map[string]string from a simple unit style resource file
./sample
[sample]
key1 = value1
key2 = value2
[sample2]
# comments are supported as are colon seperators and
# multi-segemented values are not disturbed on parse
key1 : value1
key2 : value2,value3,value4
key3 : value3:value4:value5
key4 : value4=value5
var u unit.Unit
u.Parse("./sample", "sample")
// u = map{key1:value1, key2:value2}
fmt.Println(u)
