FileSys

Overview
FileSys is a language which stores and manipulates all of its variables as files on the file system instead of in memory locations in the traditional sense.

Files
There are four valid file types in the FileSys language
 * .a - String data in ascii format
 * .n - Numeric data in arbitrary precision decimal data
 * .b - Block, an empty file used for signalling between threads or processes
 * .f - A script of FileSys commands to be executed

Hello World
mkdir /var out "Hello World" > /var/message.a echo /var/message.a
