Range map

Very useful when its needed to make a map from a key ranging from a set of values, for example:

from	to	value
0	9	"Ones"
10	99	"Tens"
100	999	"Hundreds"
1000	9999	"Thousands"

Code example:

package main

import "github.com/AndrejfSantos/RangeMap/rangemap"

func main()  {

    rangeMap := rangemap.RangeMap[string]{}
    rangeMap.Put(0, 9, "Ones")
    rangeMap.Put(10, 99, "Tens")
    rangeMap.Put(100, 999, "Hundreds")    
    rangeMap.Put(1000, 9999, "Thousands")

    value, found := rangeMap.Get(-1)  // returns nil , false
    value, found = rangeMap.Get(1)    // returns "Ones" , true
    value, found = rangeMap.Get(42)   // returns "Tens" , true
    value, found = rangeMap.Get(666)  // returns "Hundreds" , true
    value, found = rangeMap.Get(1337) // returns "Thousands" , true

}
