	 *This is a custom text editor view for editing program code
   *It is based on a MultiAutoCompleteTextView which an extension of EditText.
   *So many of the EditText properties and methods are also available.
   *It uses regex pattern matching to implement syntax highlighting for the edited code
   *The patterns and colours are added using AddPattern(pattern, color, caseinsensitive)
   *   
	 *You must add the line '#AdditionalJar:CodeView' to your Main module attributes
   *
