<#
  Git commandline helpers for PowerShell
  Author: Damian Suess
  Revision: 1 - 2019-01-16

  Usage:
    GitPull             ; Pulls current branch defaulting remote to "origin"
    GitPull "NotOrigin" ; Pulls current branch from specified remote
    GitPull -u          ; Pull merging unrelated histories

  TODO:
    - Pulls branch and sets tracking so you can simply execute, ``git push`` next time
      GitPull "NotOrigin" -track
    - After pulling check for "fatal: refusing to merge unrelated histories" and suggest '-u' switch.
