Purpose:
Gives you the ability to capitalize the first character of each word in a string.
NOTE:  This function only changes the casing of the first character of each word.

Returns:
The string with the first character of each word capitalized.

Example #1:
The code below will capitalize the first letter of each word in the title:

var bookTitle = "jXtension - the little brother to jQuery"; var newBookTitle = bookTitle.toProperCase(); alert("The original book title:\n" + bookTitle + "\n\nThe corrected book title:\n" + newBookTitle);

Example #2:
The code below will prove that the toProperCase function doesn't change the casing of any letter that isn't the first letter in a word:

var message = "i'm the crEAtor of jxtension. i liVe in THE usa. i am a grad stU" + "DEnt at k.u. (kutztown university)."; var pcMessage = message.toProperCase(); alert("The original message:\n" + message + "\n\nThe proper cased message:\n" + pcMessage);

Take note of the following:

• The characters that start off capitalized do not get lower cased.
• The characters that should be capitalized because of their origin (e.g. "x" in JXtension), aren't capitalized.
• All letters that follow a character which isn't a letter or a digit are capitalized (e.g. "K.U").
