TypoglycemiaMain.java

// This program can be used to read words from a file and change them to a form that their interior
// letters are scrambled.
// It can show how our cognition process behind reading, known as Typoglycemia, works.
// Besides, it can also directly generate the special case that the interior letters are reversed.
// All intro text from: https://en.wikipedia.org/wiki/Typoglycemia
// (really not well organized in style..)
