// ActionScript Document
/*
This script establishes the behavior of the rollControl Movie clip.
this script/object requires an array to be populated with song URLS by an other object
this script/object requires a song index to be set by another object

the path to populate this beast will be:
_root.colgo_N.rctl_M.rgo_1.sa
_root.colgo_N.rctl_M.rgo_1.si
where N is the column number, and M is the row number.
these aren't actually x,y coordinates or anything, just a naming convention i am using.
cols increment from left to right starting at 1
rows increment from top to bottom starting at 1
