SamReads: Return a SamReads object
In jefferys/SamSeq: Work with aligned reads from a SAM file

S3 method that returns an S3 SamReads object, which is a data frame with additional meta data.

SamReads(x, ...)

## S3 method for class 'character'
SamReads(x, source = SamSource(NULL),
  splitTags = TRUE, ...)

## S3 method for class 'Sam'
SamReads(x, ...)

## S3 method for class 'SamReads'
as.data.frame(x, ...)

`x`	For the object to extract or build a sam reads object from. It can be a character vector of unparsed read lines, a `Sam` object, or (pretty uselessly) a `SamReads` object.
`...`	Future-proof the method. Not currently used.
`source`	The `SamSource` object to associate with the reads. If not provided and `x` is a `Sam` or `SamReads` object, it will default to that object's source. Otherwise the default is all missing data, i.e. `SamSource(NULL)`
`splitTags`	By default this is `TRUE`, meaning optional read tags are split out as named columns. Setting this `FALSE` leaves the optional tags as a single column, "tags", with all the extra tags presented as a single tab delimited string.
