Description
...........

Get the counts of sequences per sample for the different stages of the dada pipeline.

Usage
.....

**Inputs:**

Any number of results of dada2 steps in the following form:
- a collection of results from dada, or mergePairs; or the collection of statistics from filterAndTrim (the identifiers of the collection elements are used as sample names)
- the result of makeSequenceTable or removeBimeraDenovo

**Output:**

A table containing the number of sequences per sample (rows) for each input (columns)

Details
.......

For results from

- dada, and mergePairs the sum of the result of dada2's getUniques function is used
- makeSequenceTable, and removeBimeraDenovo R's rowSums function is used
