// AssDialogue Blocks
// ------------------
// A block is each group in the text field of an AssDialogue
// For example:
// Yes, I {\i1}am{\i0} here.
//
// Gets split in five blocks:
// "Yes, I " (Plain)
// "\i1" (Override)
// "am" (Plain)
// "\i0" (Override)
// " here." (Plain)
//
// Also note how {}s are discarded.
// Override blocks are further divided in AssOverrideTag's.
//
// The GetText() method generates a new value for the "text" field from
// the other fields in the specific class, and returns the new value.
//
// TODO: Support for {\p#}...{\p0}
