 css_summary is a function that is not provided a scope by the cleanCSS
 function.  It is intended to be provided as a closure that it can
 access the interiors of cleanCSS, but remain accessible outside
 cleanCSS.  This function returns the number of HTTP requests from the
 beautified CSS and what those requests are.

 Arguements:

 * x is the source code input
 * size is the character size of an indentation
 * character is the character that makes up an indentation
 * comment determines whether or not code comments should be indented
 to match the code or whitespace collapsed and left justified if
 passed the value "noindent"
 * alter is whether or not the source code should be manipulated to
 correct some violations
