[boost] [review] [heap] ending today

Today is the last day of the review of Tim Blechmann's Heap library. The review had been extended until today because of an unavoidably late announcement. If you commented on the library, please submit a formal review (i.e., a Yes/No vote). There have been a number of people expressing comments or asking questions, but not voting. I will be preparing a summary of the review over the course of the week so there is a little extra leeway if you absolutely cannot submit a formal review today. I would like to thank all of the reviewers who have have taken time to inspect and comment on Tim's work. I would also like to thank Tim for submitting his library for review and patiently answering our questions and addressing our comments. Andrew
