Quick reading of file info, avoiding large items #29

filereader.ReadFileMetaInfo() can avoid reading a whole file but only gives limited information. Should add the ability to still read all information but delay reading of large values (e.g. pixels, dose grid) until actually needed. Possible solution: have a flag in Attribute instance to mark whether has actually been read in. A danger of this is that one has to re-open the file to read those values ... if any changes have been made to the file then this could be dangerous. Will need a flag for date/time stamp and/or recheck the instance UID to make sure is same file.

Looked at an iterator solution as a way of giving more freedom in partially reading a file -- posted test file fileiter.py to the pydicom google group. This file uses a generator to return one data element at a time, and example code for stopping after reading a list of certain desired items.

Re-opened the issue to deal with the common request to stop reading before big data. The fileiter.py example could be a starting point for this.
