function mkrepo() {

####################################################################################################
# OVERVIEW
# This function wraps $ git init <directory> with a script giving the option to automatically
# connect <directory> with a remote repository on GitHub.
#
# OPERATION
# $ mkrepo -r <directory> sends a call to the GitHub API to create a new remote repository (called
# <directory>) from a pre-defined template. The script then Git-initializes a new or existing local
# <directory> and links it with the newly-created remote repository.
#
# $ mkrepo <directory> simply initializes <directory> (new or existing) as the root of a local Git 
# repository without connecting to the GitHub API.
#
# For the script to work, Curl and Git need to be installed, and the following variables need to be 
# set in the active shell environment.
#
# GITHUB_USERNAME
# GITHUB_TOKEN
# GITHUB_TEMPLATE_REPO
#
# DIRECTORY BEHAVIOR
# $ mkrepo [-r] <directory> -- makes <directory> (new or existing) the root of a Git repository 
# inside the current working directory.
# $ mkrepo [-r] <path>/<directory> -- makes <directory> (new or existing) the root of a Git 
# repository inside the <path> destination directory.
# $ mkrepo [-r] -- makes the current working directory the root of a Git repository.
