[priority queue](https://en.wikipedia.org/wiki/Priority_queue) implementation in golang where every element in the queue can be accessed by its index in constant time.\nThis is achieved by using Golang's [sort](https://golang.org/pkg/sort/) package. \n\n\n## Usage\n\n```bash\ngo get github.com/kyroy/priority-queue\n```\n\n```go\nimport \"github.com/kyroy/priority-queue\"\n````\n\n```go\ntype Data struct {\n\tvalue int\n}\n\nfunc main() {\n    queue := pq.NewPriorityQueue()\n    \n    // Insert\n    queue.Insert(Data{value: 7}, 3.5)\n    queue.Insert(Data{value: 7}, 5.)\n    queue.Insert(Data{value: 123}, 2.5)\n    \n    fmt.Println(\"len\", queue.Len()) // len 3\n    \n    // Get\n    for i := 0; i \u003c queue.Len(); i++ {\n    \td, prio := queue.Get(i)\n    \tfmt.Println(\"get\", i, d, prio)\n    }\n    // get 0 {123} 2.5\n    // get 1 {7} 3.5\n    // get 2 {7} 5\n    \n    // Pop...\n    d := queue.PopLowest().(Data)\n    fmt.Println(\"d\", d) // d {123}\n    d = queue.PopHighest().(Data)\n    fmt.Println(\"d\", d) // d {7}\n    \n    // Len\n    fmt.Println(\"len\", queue.Len()) // len 1\n}\n```\n\n\n### WithMinPrioSize\n\n*Note: Equivalend for `WithMaxPrioSize`*\n\n```go\ntype Data struct {\n\tvalue int\n}\n\nfunc main() {\n    queue := pq.NewPriorityQueue(pq.WithMinPrioSize(2))\n    \n    // Insert\n    queue.Insert(Data{value: 7}, 3.5)\n
