Apply basic formatting

Browse Source 
- Do not align assignments on equals signs
 - Use spaces before opening curly braces
 - Add spaces between parameters as necessary
 - Insert newlines between method declarations
 - Other minor changes

This formatting pass is not comprehensive. For the most part, it does
not deal with Javadoc formatting, line wrapping, parameter alignment
rules or a number of other items that can be addressed later.
