Wilmington: Third Edit

I decided to contribute to the Education Institution section of the wikipedia article by adding the following schools: Albert Einstein Academy, Wilmington Montessori, St. Mary Magdalen, St. Anthony Grade School, and the Immaculate Heart of Mary School. These are all private grade schools that are not high schools. Previously the article only listed grade schools that were public, and private grade schools that were also high schools. Now parents using wikipedia as a source will have a more complete list of schools to choose from to send their young ones to.
I also rearranged this section since it originally had two paragraphs, one discussing public schools, and the other one discussing both private schools and charter schools. I thought this was misleading since charter schools(free to parents) and private schools are different, so I split the second paragraph into two.
