Highlight entries in the Dictionary that use known kanji

[fabd]

Using the user's flashcard set we can highlight entries in the DIctionary which are only made of known kanji. (we assume here that the user is already familiar with hiragana and katakana).

In this example the user has learned RTK kanji 1 to 50. The second word is not highlighted because "large" 大 is 112. When the user learned 大 , the second entry will also be highlighted. Thus as the user studies more kanji over the weeks and months, the dictionary lookup will highlight more entries, always building on the previous knowledge.
