input is a sentence, using only letters and spaces, with a period allowed only
if it is the last character.
*Capitalize the first letter of the first word, if it is not already (The
first character of the first word is the first non-space character).
*Compress any consecutive spaces into one space and remove any spaces at the
beginning or end of the sentence (remove all spaces before the first non-space
character and after the last non-space character).
*Finally, ensure that there is period at the end of the sentence. If not,
append a period to the end of the sentence.
