'for' loop may be replaced by 'while' loop

Reports for loops that contain neither initialization nor update components, and suggests converting them to while loops. This makes the code easier to read.

Example:

for(; exitCondition(); ) { process(); }

After the quick-fix is applied:

while(exitCondition()) { process(); }

The quick-fix is also available for other for loops, so you can replace any for loop with a while loop.

Use the Ignore 'infinite' for loops without conditions option if you want to ignore for loops with trivial or non-existent conditions.
