Next 1.4.0 update

[eleev]

The next update will include the following extensions:

Foundation

Custom Types

• ObjectPool - thread-safe implementation of ObjectPool design pattern
• Observer - thread-safe implementation of Observer design pattern (don't confuse with NotiifcationCenter - it's an implementation of Publish-Subscribe pattern)
• MulticastDelegation - non thread-safe implementation of MulticastDelegation design pattern

Extensions

Date

• Date+FirstLast - adds a number of properties that allow to quickly access: first day of a week, start of a day, end of a day and a number of days in a month
• Date+PreviousNext - adds properties that allow to get access to the previous and next days

Array

• Array+Remove - a set of methods that remove Element form an array by mutating it
• Array+InsertionSort - adds support for Insertion Sort algorithm
• Array+MergeSort - adds support for Merget Sort algorithm
• Array+QuickSortHoareScheme - adds support for Quick Sort algorithms using Hoare's partitioning scheme
• Array+QuickSortLomutoScheme - adds support for Quick Sort algorithm using Lomuto's partitioning scheme
• Array+BubbleSort - adds support for Bubble Sort algorithm
• Array+ShellSort - adds support for Shell Sort algorithm
• Array+RadixSort - adds support for Radix Sort algoritm

Sequence

• Sequence+Count - counts the number of occurrences of a logical expression

Grand Central Dispatch

• Atomic - guarantees that a valid value will be returned when accessing such property by using multiple thread
• Mutex - used to proptect shared resources. A mutex is owned by the task that takes it. In a given region of code only one thread is active
• ReadWriteLock - a synchronization primitive that solves one of the readers–writers problems
• UnfairLock - a lock which causes a thread trying to acquire it to simply wait in a loop ("spin") while repeatedly checking if the lock is available

The update also brings support for Swift 4.2 and adds minor changes that guarantee conformance to the latest SDK.
