 ====== Generic Notecard Reader ======
-This is a generic notecard loader. In this variation, it does not set a timer to check whether the notecard has been loaded. Thus, all the notecards should have an ending newline for this system to work properly.

 Remarkably, the expression preserves the same type constraints that a ternary operator would have: the type of ''a'' will be the same as either elements of the list (in this case converted via ''llList2String'') and the type of the variables ''c'' and ''b'' are free under the contraints of variables ''a'' and the values that ''a'' will hold (however, variables ''c'' and ''b'' must be of the same type).
