Tab completion for your Julia REPL.

• Names of variables and functions defined or imported to the global scope.
• Names of variables and functions defined in the current cell/string.
• Methods of a function if inside a function call.
• Importable modules after using \t
• Help for function if pos is at the beginning of a function call

• Accessible command line programs
• Arguments for common programs (like git pull, push, commit, checkout)

The interface is very simple. There are two exported methods provided:

	completions(string,pos)
	shell_completions(string,pos)

The former provides completion of julia expression while the latter provides completion of julia shell syntax (; at the standard REPL or inside backticks).

Both functions have the same return format:

	results, range = completions(string,pos)

The first return value is an array of possible completions, while the second return value is a range specifying the part of the string that was matched. In particular this means that to execute a completion, you should replace string[range] by completion[i] for some i.
