Major Refactor | Added Functionality | Testing

Tested createRedis(), getRange().
Encapsulated everything into separate functions.
LPUSH works.
Ran into a silly error, forever immortalized on Stack Overflow:
http://stackoverflow.com/questions/19549449/lpush-function-in-redis-php-throwing-boolfalse-when-i-get-dump-list
Still need to ensure that the rest of the functions are firing and
outputting correctly.
