PARTIAL commit; new, simpler rodRefSeq will reappear in a seq.
git-svn-id: file:///humgen/gsa-scr1/gsa-engineering/svn_contents/trunk@1694 348d0f76-0448-11de-a6fe-93d51630548a
all the updated classes now make use of new SeekableRodIterator instead of RODIterator. RODIterator class deleted. This batch makes only trivial updates to tests dictated by the change in the ROD system interface. Few less trivial updates to follow. This is a partial commit; a few walkers also still need to be updated, hold on...

- Some walkers don't use the ref base, so speed up traversals by not requiring it

Also, sanity check that ref is not 'N'.

The main reason for the change is that there can be (and are!) multiple RODs overlapping with a single reference base position in a single track. There can be two "trivial" RODs at the same location (e.g. samtools pileup will have two point-like records at putative indel sites: one for the reference, the other one for the indel itself). Or there can be one or more "extended" RODs (length >1), eg. dbSNP can report an indel at Z:510-525 AND a SNP at Z:515.
The ReferenceOrderedDatum object (and children) will not be changed, but it is now explicitly interpreted as a single data *record*, possibly out of many available from a given track for the current site. As long as single data record occupies one line in a data file, the new ROD system will take care of loading and keeping multiple records, including extended (length > 1) ones, and will automatically drop the records when they finally go out of scope. For one-line-per-record, multiple-records-per-site RODs, there is no need anymore for the hack used so far that involved passing ROD's own implementation of iterator through reflection mechanism (though it will still work)
* RODRecordList:
the ROD system (its iterators) will now always return a LIST of all RODs available at current position or at current query interval (see below). This class is a trivial wrapper for a list of ROD objects, with added location argument for the whole collection. The location of the RODRecordList is where the ROD system is currently sitting at: a single, current base on the reference (if next() traversal is performed), or the location of the query interval when returned by seekForward() (see below). The ROD objects themselves will have their locations set according to the original data in the file. Hence, perusing the above example of a dbSNP indel at Z:510-525 and SNP at Z:515, when moving to the position Z:515 the ROD system will return a RODRecorList with location Z:515, and with two ROD objects packaged inside, one with location Z:510-525, the other with Z:515.
*RODRecodIterator:
Almost identical to old SimpleRODIterator used by ReferenceOrderedData; this is a low-level iterator that walks over records in the data file (with a callback to ROD's ::parseLine() to parse real data)
*SeekableRODIterator:
a decorator class that wraps around Iterator<ROD> (such as RODRecordIterator) and makes the data traversable by reference position, rather than record by record. This is reimplementation of the old RODIterator. SeekableRODIterator's ::next() moves to the next position on the ref and returns all RODs overlapping with that position (as a RODRecordList). This iterator also adds a seekForward(loc) operation, that allows fast forwarding to a specified position or interval. Length > 1 query arguments (extended intervals) are fully supported by seekForward(), the returned RODRecordList wil contain all RODs overlapping with the specified interval, and the location of the returned RODRecordList object will be set to that query interval. NOTE: it is ILLEGAL to perform next() after a seekForward() query with length > 1 interval. seekForward() with point-like (length=1) interval reenables next().
