* added description for functions

* fixing comparison

Currently useless at the moment, however, because there aren't any builtins that are worth piping, but the feature can be tested with the following command:

help | grep alias

Add script arguments, implement -c similarly to bash

The support for expanding values in command substitutions was basically nonexistent.
With this change, command expansion will finally be much more useful now that values
will be expanded before commands are spawned

Previously, when no pattern is supplied, a string will be split by spaces. This change
will extend that so that all whitespace characters will be considered in the pattern
for splitting.

This change will merely refactor the ArrayMethod into it's own structure
in orher to reduce the complexity of the expand_string function.

Added some additional tests and fixed some discovered parsing bugs.
The following command will now work as intended:

echo @[cat /proc/cpuinfo | grep "model name" | head -1][3..]

This commit contains a decent number of tests, and implements support for the string methods like so:

let a = [ 1 2 3 4 ]
echo (a, ', ')

I should have support for array methods and some additional tests landed tomorrow.

With this change, arrays may now be sliced by ranges.

let array = [ 1 2 3 4 5 ]

echo @array[2..3]
echo @array[2...3]
echo @array[..3]
echo @array[3..]
echo @array[..]

Implements the following syntaxes:

let a = [ 1 2 3 ]
echo @A[0]
echo @A[1]
echo @A[2]

echo @[echo 1 2 3][0]
echo @[echo 1 2 3][1]
echo @[echo 1 2 3][2]

echo [1 2 3][0]
echo [1 2 3][1]
echo [1 2 3][2]

Next up: array range slicing
